Question

What is 1 board foot equal to?

a) 1 inch length x 1 inch width x 1 inch thickness
b) 12 inches length x 12 inches width x 1 inch thickness
c) 1 foot length x 1 foot width x 1 inch thickness
d) 1 meter length x 1 meter width x 1 centimeter thickness

Answer 1

A board foot is equal to the volume of a wood piece that measures 1 foot in length, 1 foot in width, and 1 inch in thickness. The correct option is c) 1 foot length x 1 foot width x 1 inch thickness.

Step-by-step explanation:

The term board foot is a unit of volume used in the lumber industry to measure the volume of wood. One board foot is equivalent to a volume of one square foot that is one inch thick. Therefore, the correct answer is c) 1 foot length x 1 foot width x 1 inch thickness. This definition aligns with the customary units of lumber measurement where 12 inches make up a foot.

To visualize a board foot using something familiar, consider that a board that is 12 inches long, 12 inches wide, and 1 inch thick would be equivalent to one board foot. This is because you would multiply the length (12 inches / 1 foot) by the width (12 inches / 1 foot) by the thickness (1 inch), resulting in one board foot, as per the calculation formula:

Length (in feet) x Width (in feet) x Thickness (in inches) = Board feet

In this case: 1' x 1' x 1" = 1 board foot.
