How correctly to calculate the cubing of lumber?

In many cases, when building and repairing buildings, lumber is used. They are suitable for various types of work. Not an exception is the decoration of the room and the building as a whole. However, in the first place, it is necessary to calculate the cubic capacity of the lumber.

Process of calculation

As an example, take a room with an area of one wall 18m², where the width of the wall is 6 m, and its height is 3 m. The total area will be as follows: 18 m²x4 = 72 m². In this case, 4 is the number of walls. Let's proceed to the calculation.

• Calculation of the cubature of sawn timber for walls is determined by multiplying the wall area by the thickness of the board. In our example, this will be 72 m ² x 0.03 m = 2.16 m ³, where 0.03 m is the thickness of the board.
• Similarly calculate the amount of interior finishing of the house.
• Calculation of the cubic volume of sawn timber for the floor, ceiling and roof is made in the same way as for the walls.
• The volume of the beam for the frame of the house is obtained by multiplying the cross-sectional area of the beam (column) by the length and by the number of racks provided for by the project of the house.

The specific complexity of selling and buying lumber is the correct calculation of cubature. Even the controlling authorities do not always manage to check whether the calculation is performed correctly. Lumber from the manufacturer is supplied in the original packaging. It accurately indicates the volume and cost of products. If this is not the case, the buyer has to doubt whether the calculation of the cubic capacity of the lumber and its cost has been carried out correctly. The quality parameters of the boards are regulated by GOSTs, technical requirements, and various regulatory documents. It all depends on what kind of tree they are made of, what they will be used for. To determine the volume of round lumber, the corresponding GOST is also used.

Additional calculation parameters

In the woodworking industry, the concepts of a dense and storage cubic meter are used. To transfer one value to another, a conversion factor is applied. For example, an edging board in value price lists is indicated for calculating volumes in a dense mass. This calculation is not difficult. For this, the indicators of the storage cubic meters are converted into dense masses using a special coefficient.

Measurement and calculation rules

For example, the croaker is sorted first in length by 2 species - up to 2 meters or more. Then it is stacked. At the same time, thin and thick ends alternate. The stack is stacked as tightly as possible. The height and length must be the same. Also it is necessary to withstand right angles in the pile. Multiplying the length, width and height of the package, we get a storage cubic capacity.

Tip

It will be useful to also know that the measurement rules for each type of sawn timber are regulated by the corresponding GOST. It contains tables for calculating the volume of products. When selling a building beam or a board, measure each piece of lumber, according to the tables in the GOST, calculate the volume of edging lumber. You should also know that to determine the number of boards in 1 cubic meter you need to calculate the volume of one board. This calculation is not difficult. Then we divide the unit by the volume of one board and obtain the required number of products.
