Many during the construction of the house or baths face the need to calculate how many sawn timber will be required for work. Determine how much the board or timber is needed, simply. But the price of sawn timber is usually indicated for a cubic meter, and in this case it will be more convenient to use for the calculations with a special program. With the help of our site, you, knowing the length, width and thickness of the board, as well as their number in pieces, can calculate how many cubic meters of lumber you will need and how much one cubic meter or one board will cost.
Scope of application
Timber are called so because they are obtained by sawing the trunk of the tree. Timber for construction, manufacture of furniture, diverse containers and other products are applied. Today, this type of building materials is the most popular. Wood from which lumber is made is an excellent heat insulating material, supports stable humidity and does not require special processing and care, which makes it particularly comfortable.Types of sawn timber
The sawn timber includes a timber, edged board, unedged board, construction rails. The bar is a log handled from all sides. In the cut, it has a square or rectangular cross section. The most widely pace is used in the construction of houses, baths and overlap designs.The edged board is a universal lumber, which is actively used both in construction work outside the building and when designing internal space. The edged board in the section is an elongated rectangle. The unedged board differs from the edged the fact that the edges are not cut off, so the layer of tree bark remains visible, from which this board was cut out. The construction rack or bar is a bar, a smaller cross section than the usual, and is widely used in construction.
Lumber differ in the type of wood, from which are made. They make them made of coniferous trees, such as pine, spruce and larch. And from solid wood, such as oak and beech, birch, aspen.
There are lumber as much moisture. They are divided into raw moisture levels of more than 22 percent and dry with humidity below 22 percent. The first are used for construction work, and the second for the manufacture of furniture.
Several varieties of sawn timber are also isolated. The selection of the variety depends on the scope of application. So, the furniture uses the materials of the highest grade. For carpentry and handling goods, timber 1 grades are suitable, and 2 and 3 grades are used exclusively as a construction board. Lumber if they are not used for a long time, you need to protect against moisture exposure. This can lead to them. It is not recommended to store sawn timber laid on each other. Between the layers of bars or boards must be gaskets.
The unedged board has a large run in the width at opposite ends, so when calculating the unedged board in the formula you need to substitute the average width. The average width of the unedged boards is measured in the middle of the length as a half as a width of both plasters (ends of the board) without taking into account the bark and the beam. The measurement result is rounded up to 10 mm, the shadow of up to 5 mm is not taken into account, and the shares of 5 mm are more considered for 10 mm.
Unedged board: what is it
Unedged board are the first board taken from the barrel. Her edges are not torn and have a conversion, which is unacceptable for the edged board. Unedged boards bark on the side edges. The first, removed from the barrel board has the most bark. Standard thickness of unedged boards 25, 40, 50 mm, and length - 6 m. Unedged boards are the cheapest of all boards. Therefore, they are used for forests, sheathing, roof crates, components of carrying structures, flooring, rough floors, on firewood. In order for the unedged boards to start rotes with them, you need to remove the bark, dry and process the antiseptic.
In the process of private construction, such as a house, garage or giving probably no builder without lumber. Even if the house is erected from the most fashionable and modern materials, replace part of wooden structures, such as rafters, lag, crates for example on plastic or metal is impossible, or economically unprofitable.
For the construction of a small house or bath, you will probably need a minimum of several cubic meters of lumber of various sizes and sections, ranging from the board and ending with the bar and slats. If the construction is quite large, then the wood account is already on dozens of cubic meters.
On a large-scale construction site, usually the number of certain types of boards or timets has already been made in the estimate and builders there is no need to calculate them or not for construction, but what to do those who build a small house with a limited budget?
If he buys more lumber than you need, where to give the remnants? In order to assist these people in the calculation of sawn timber and their number, we decided to write this article. We proceeded that for small buildings, the counting of sawn timber is made either individually, or in a prayer, therefore, in the tables, the cross-section of boards and bars are specified in the tables, as well as their length. Also indicated the volume of a particular lumber in cubic meters.
This is done so that a person can count the desired number of boards or bars in cubic meters, as in the main mass of the company who sell sawn goods release them in cubic meters. If you buy, for example, the boards pieces in a construction store - there is a final price will be 1.5 - 2 times higher, which is absolutely unprofitable for the buyer.
Additionally, we led data for the so-called non-standard sawn timber, because many firms are carried out by cutting forests in the size of the Customer and these dimensions may differ from the standard (usually it is dictated by issues of savings or constructive features of the erected structure).
Indicating the number of sawn timber In one Cuba, we gave a digit of one-piece boards or bars, so it is more accurate to use the data on the volume of the specific type of sawn timber, multiplying them by quantity.
For private construction, information on the number of boards or bars in one Cuba is very helpful. Buying a few cups of the board you will know how much in this volume of boards, which will also help you recalculate them when receiving, that is, you are not deceived with the amount.

Before proceeding with the construction, it is necessary to determine the desired amount of material. This parameter will be needed for the purchase of raw materials and products, in most cases it also participates in engineering calculations. In the article we will analyze how much the board in Cuba.
Views of lumber
To date, wooden products for construction are presented in a variety of variations: components for the construction of walls and individual structures (bars, logs), various panels (DVP, chipboard, OSP), elements for finishing and cladding. Therefore, it is worth starting with what can be the boards:
How many boards in a cube of any kind are determined by the same way regardless of the variety of wood and the degree of processing. Exceptions are unedged boards. Next, consider methods of calculation.
Concept of volume
Everyone with school benches is known that 1 m 3 \u003d 1m x 1m x 1m (length * width * height in meters).
Since the elements of the battery or species have the same dimensions, how many pieces of boards in Cuba can be determined, knowing the volume of just one. At the same time, it is not necessary to represent a physical figure with the parties of 1 meter, the actual volume of the product is hidden under the concept. It is used when buying and selling, counting the total volume of construction and constructive calculations.
Determine the number
Everyone knows that the 1 meter-length boards are extremely rare, their main working length is 3, 4 or 6 m. It should be borne in mind that there are sawn timber with a reserve to 10-25 cm. In some cases, the seller neglects this size, but In most cases, it is taken into account when counting. Therefore, pay attention to this in order not to question the overpayment. Height and width indicate exactly in millimeters. The final dimensions look like this: 25x200x6000 (height * Width * Length in mm). To transfer the values \u200b\u200bto meters, it is necessary to divide the values \u200b\u200bper 1000, we obtain: 0.025 * 0,200 * 6.0 (m). We multiply the values \u200b\u200bbetween themselves, we get: 0.025 * 0,200 * 6.0 \u003d 0.03 m 3.
Since all boards have the same form and parameters, determine how many boards in Cuba: 1: 0.03 \u003d 33.33 pieces. Round up to whole units, we get 33 products. Here you can count the cost of 1 boards: if 1 cube costs 6500 rubles, then the element of 0.03 m 3 will cost only 195 rubles. Armed with these knowledge, you can send to the store.
Unedged materials
The boards and bars of this type have untreated side faces, as these are the first layers taken from the tree trunk. Thus, the width parameter cannot be determined uniquely. How, in this case, count, how many boards in Cuba?
Take a sample for example, which has a different width from both ends: 20 cm on one side and 30 on the other. In such a situation, they take the average value of the indicators, in our case - 25 cm. Next, the volume of such a board is determined by the already known formula.
When there is a need to buy a large number of elements, they are placed in stacks in such a way that all sizes are assessed as much as possible (the difference is no more than 10 cm). Next, simple measurements are determined by the length, the height of the stack, the width of the middle part, multiply them into the coefficient, taking into account the air clearance: 0.07 ... 0.09 (more clearance is less than the coefficient). Thus, learn how many boards in 1 Cuba of the Unedged Lumber.
The main dimensions of such boards: 25, 40, 50 mm in height and 6000 mm in length. Other parameters are rarely specified, mostly for personal order. This is due to low demand for products and the specifics of their use. Such are purchased for the construction of scaffolding, roof crates, devices of various flooring, as well as on firewood. For these purposes, it is long boards that can be trimmed as needed.
Pay attention to the little things
To buy wooden products and do not overpay the unscrupulous seller, use the above formulas and independently count the desired number of boards. A simple example: you received the actual volume of 1 element 0.035 m 3. Suppose 1 cube costs 6000 rubles, then the board will cost 210 rubles. But if the seller rounds thousandth to hundredths, will come out 0.04m 3, then for the product will have to pay 240 rubles. Maybe, for one board, the difference is not so significant, but often lumber is bought in large quantities, then the difference in price can do a few hundred rubles. How many boards in Cuba - it is advisable to know for sure.
Eliminating calculations
To do not determine the volume of products every time, you can use ready-made data. Manufacturers have calculated how much the board in Cuba: the table compiled by the measurement results helps determine the required amount of material. In such directories, there is data on different types of products, they are combined into the main sizes. There are separate reports for boards, bars, platbands, plinths and other existing, they are actively used not only inhabitants, but designer engineers and builders.
Now consider how many boards in 1 cube. The table is composed for edged products.
Height * Width * Length, mm | V 1 boards, m 3 | Whole pieces in 1 m 3 |
As you can see, in the directory there is a precise number as the board in Cuba. The table takes into account the shares of up to thousands, which is important to take into account when buying and other calculations.
Non-standard
For construction and economic purposes, neatly processed products are not always used. Sometimes it is advisable to purchase an unedged material, the volume of which is not easy to calculate due to a specific uneven structure of the product. For these cases, there is also a solution - ready-made reference reports, from which you can find out how many boards in 1 Cuba. The table for them is made up by the main averaged size.
Tabar data are referenced and may differ slightly from the actual: it has already been said, the products may differ in size for a couple of centimeters in length, for example. Therefore, every time you should pay attention to specific parameters.
No matter what timber is necessary for construction. It is necessary to be able to independently determine the desired volume with the use of formulas, calculator and tables. This will help to avoid acquiring the extra number of boards and significantly save the budget.
Meters are robust, square and cubic. Studdered great construction or even small repair, you should clearly navigate in these terms. The ability to correctly translate the number of one or other materials into robes or cubic meters will serve excellent service with preliminary calculations of the cost of planned repair or construction. For example, clearly understanding how many square meters in one roll of wallpaper, you can quickly calculate their quantity required for the room pasting or the entire apartment.
Calculations can be done in cubic meters, square or route meters
If the upcoming repair or construction is associated with the use of wooden materials, it is necessary to thoroughly examine recalculations from the route meters into cubic, as prices can be presented in the market, both beyond the unit of material and for one cubic meter. The number of timber in Cuba varies and depends on its cross section. The easiest way to find out how many boards in Cuba is a table, but if it does not have to remember the formulas.
What is a cubic meter
The cubic meter (abbreviated m³) is a unit of volume and is equal to the volume of the cube with a length of the edge of 1 meter. In accordance with GOST 8486-86, wooden materials must have measured section sizes and lengths, making it easy to calculate the number of boards included in the material cube.
To determine the size of the section, it is necessary to retreat from the end of the bar for a distance of at least 10 cm and measure the width and height of the beam. Multipling these values \u200b\u200bto each other, it turns out the cross-sectional area of \u200b\u200bthe beam, which is multiplied by the volume of one bar. Having calculated the number of bars in one cubic meter, you can easily navigate between the cost of one beam and one cube beams.
The cubic meter is equal to the volume of the cube with a side of the edge 1 m
Calculation of sawn timber for construction before purchasing them
Of course, the easiest way to come to the developer to explain what I want to see in the final version and agree to the proposed project. But, if you independently understand the calculations of the required amount of sawn timber, then at the stage of discussing the value of materials and work on the construction of the house, it is possible to navigate how real prices the construction company offers.
Many developers calculate the required amount of material in the cubes, some consider the piece of magnitude, taking the standard of length - 6 or 12 m. A clear understanding, for example, how many timber in Cuba 150x150x6000 will protect against overpayments.
Standard Bar 0.15x0,015x6 meters
The procedure for calculating the number of timber in Cuba
Despite the same principle of calculations, there are certain nuances in the definition of the cube and the number of different sawn timber.
1. Basic formulas for calculating the number of bars in Cuba
To determine how many boards in Cuba, with the bars of a certain section, you need to know the three measured parameters: length, width and height. First, it is necessary to calculate the volume of one bar according to the formula V \u003d A * B * L (here V - volume, m³; a - height, m; b - width, m; L - length, m)
Brous Parameters: Length, Width, Height
How many pieces of timber in Cuba is determined by the formula:
Where, and - the number of timber in Cuba, pcs.;
1 - one cubic meter, m³;
V is the volume of one bar, m³.
2. How to determine how many pieces in Cuba BROUS 100x150
In the prices of construction companies for convenience, the cross section of the bar is indicated, that is, its width and height, for example, 100x150. Where 100 is the width indicated in millimeters, and 150 - height. The length is most often 6 meters, or 6000 mm.
The volume of the bar 100x150x6000 will be 0.09 m³.
V \u003d 0.1 m * 0.15 m * 6 m \u003d 0.09 m³. Here 0.1 - width, m; 0.15 - height, m; 6 - Length of Bruus, m.
How much in that case in one cubic meter "fit" the material can be found by dividing the cubic meter on the volume of one bar:
Where, 1 is one cubic meter, m³;
0.09 - Dued volume of one bar 100x150x6000, m³.
Characteristic form of cross section of a bar 100x150
So you can easily calculate how many vehicles in the volume of material purchased by moving the number of pieces per number of cubes. For simplicity and speed of counting, you can use the table: how many bar in Cuba table 6 meters.
3. How many edged board in 1 Cuba
A similar situation in calculating the amount of edged board in 1 cubic meter of wood. For example, the board used has the following parameters 100x25x6000 (width, height, length).
The volume of one board will be 0.015 m³.
V \u003d 0.1 m * 0.025 m * 6 m \u003d 0.015 m³
Quantity in 1 Cuba:
That is, the cubic meter contains at least 66 boards. When buying a cutting board cube 100x25x6000, 67 pieces should work out, rounding is on the biggest. For example, when buying three cubes should be at least 201 pieces, and when buying six - 401.
4. How many in 1 cube centerboard board
The flooring board for the best installation has the entire length on one side of the groove on the other - spike. When calculating the volume of one board, its length is taken into account, height and net width, that is, the width without taking into account the protruding spike. For example, the size of the board reflected in the figure below is 28x90 mm.
Point floorboard
With the length of the board of 6 meters, its volume will be:
V \u003d 0.09 m * 0.028 m * 6 m \u003d 0.01512 m³
Quantity in 1 Cuba:
5. How many wooden lining in 1 cube
By design, the lining remotely resembles a floor-board floor. It also has a "groove spike" compound, ventilation grooves, but the front side of the lining can have squeaks, roundings and even a convex surface, imitating the timber.
For the calculation, the "clean" width is used, that is, the size without taking into account the spike, the maximum value in the board cross section is taken as the height.
Types of lining with a visual example of the measurement of the width and height of the board
The most common size of the lining is 100x14. With the length of the board of 6 meters the number of lining in one Cuba will be at least 119 pieces:
Volume of one board:
V \u003d 0.1 m * 0.014 m * 6 m \u003d 0.0084 m³
Quantity in 1 Cuba:

What else to take into account when counting the sawn timber
One of the nuances in the production of lumber is their technological length, that is, the declared six-meter board in practice turns out to be longer by 5-10 cm. This deviation is called technological and when calculating the board meters, the board is not taken into account. The seller no one has the right to plus them into the total length of the board.
When buying a bar of a certain section, it is important to measure the parameters for acceptance or loading, since the slightest deviation even in 1 cm leads to huge losses, especially with large purchasing volumes.
In addition, it is important to remember about the weight of the procured material, which depends on the density of material and humidity.
An example of calculating the weight of the bar based on the known density of the tree (for the material of various humidity it is necessary to substitute the corresponding values \u200b\u200binstead of 860)
Tables for quick counting volume of timber
Below are the cribs to quickly find out how many bar in Cuba - the table contains not only the quantitative values \u200b\u200bof the units of the material in the cubic meter, but also the volumetric values \u200b\u200bof the bars of different sections. For example, it will show how many boards in Cuba table - 6 meters or 3 meters long will be a board or timber.

Features of storage of sawn timber
To build a house from wood, it is important to properly store the material so that its humidity is within 12%, if the humidity is higher, then the shrinkage of the construction will take place slower.
Here are a few rules that need to be remembered when storing sawn timber:
Place for storage should be smooth and dry.
To prevent moisture from entering from the surface to the site under the first bed of material, pallets are laid, which can be replaced by trimming boards or sleepers.
The distance between unit products should be withstanding within at least 2 cm for better air circulation.
After 1-2 rows, the crossbar is put across the length, which can act as all the same bouts of the boards.
If there is no possibility of building a canopy over the site for storing materials, preventing from atmospheric precipitation, the stacks are covered with a film, excluding the shutting of the ends in order not to create an inside the effect of the greenhouse.

Conclusion
Knowledge of the rules for calculating the required volume of building materials will help save time and money, or simply make sure of the conscientiousness of the developer. Therefore, if there are no quick translation skills of some values \u200b\u200bto others, then when discussing the required number of building materials, you need to keep at least a crib in the form of a table-cubature.
