A board foot is a measure of the ___ of lumber.

• A. Weight
• B. Volume
• C. Density
• D. Length

Answer: (B)

A board foot measures how much space a piece of lumber occupies. It is a unit of volume, not weight, density, or length by itself. One board foot represents the volume of a board that is 1 inch thick, 12 inches wide, and 12 inches long. This makes it possible to price and compare lumber based on how much material there is, regardless of the wood’s weight or species. The usual way to calculate it is thickness (in inches) times width (in inches) times length (in feet), all divided by 12. For example, a board 2 inches thick, 6 inches wide, and 8 feet long has (2 × 6 × 8) / 12 = 8 board feet.
