If you are working in the forestry or wood industry, you may need to calculate the volume of round wood pieces, such as logs, firewood, or timber. One way to do this is to use a table of volume (cubaj) that shows the volume of a cylindrical piece of wood based on its length and average diameter. Tabele De Cubaj Pentru Lemn Rotund 42.pdf is a book that contains such tables for different lengths and diameters of round wood, as well as other useful information for wood practitioners.

According to Paul A P I S GABOR-ILIESCU, the author of the book, Tabele De Cubaj Pentru Lemn Rotund 42.pdf is “the most visible and easy to use table of volume in Romania”. The book has a colorful, flexible, and brochured cover that makes it easy to carry and use in the field. The tables are printed in a clear, simple, intuitive, and fast format that allows the user to quickly find the diameter (sometimes using the circumference), length, and volume of the trunk. The book also provides a method for finding the diameter based on the circumference, which can be useful when measuring round wood with a tape measure.

The book covers lengths between 0.5 and 8.1 meters, with a step of 10 cm, and diameters between 6 and 100 cm, with a step of 1 cm. The volume is expressed in cubic meters [mc], with 3 decimals. The book also includes tables with practical data for wood exploitation and valorization activities, such as:

• The common and scientific names and abbreviations of forest species;
• The periods of harvesting and collecting wood;
• The maximum duration of harvesting and collecting wood;
• The periods for exploiting wood mass from forests;
• The categories of wood material; densities/specific mass;
• The calorific value (indicative) / forest species;
• The value of the factor “k” by species or groups of species, for different categories of diameters;
• Wood construction materials – types, names, dimensions – informative;
• A coupon for free registration on pepiniere.ro website.

Tabele De Cubaj Pentru Lemn Rotund 42.pdf is a valuable resource for anyone who needs to estimate the volume of round wood pieces accurately and easily. The book can be ordered online from pepiniere.ro or downloaded as a PDF file from academia.edu.

How to use Tabele De Cubaj Pentru Lemn Rotund 42.pdf to calculate wood volume:

1. Select the table that corresponds to the length of the wood piece you want to measure. For example, if the wood piece is 2.5 meters long, use the table on page 42.
2. Measure the diameter or the circumference of the wood piece at its middle point. If you measure the circumference, use the table on page 10 to find the corresponding diameter. For example, if the circumference is 80 cm, the diameter is 25.5 cm.
3. Find the row that matches the diameter of the wood piece in the table. For example, if the diameter is 25.5 cm, use the row that starts with 25.
4. Find the column that matches the length of the wood piece in the table. For example, if the length is 2.5 meters, use the column that has 2.5 at the top.
5. The intersection of the row and the column gives you the volume of the wood piece in cubic meters. For example, if the diameter is 25.5 cm and the length is 2.5 meters, the volume is 0.128 mc.

You can repeat this process for any number of wood pieces and add up their volumes to get the total volume of wood.
