What are the specified measurements of a Board Foot?

A Board Foot is a standard unit of measure used in the lumber industry to quantify the volume of lumber. Specifically, one Board Foot is defined as a volume of 144 cubic inches of wood. The measurement that equates to one Board Foot is a piece of lumber that is 12 inches long, 12 inches wide, and 1 inch thick.

In this case, the correct choice, which specifies these dimensions as 12"x12"x1", reflects the definition precisely. A piece of wood with these measurements results in exactly 144 cubic inches (12×12×1 = 144), thereby constituting one Board Foot.

Other options do not meet the criteria for a Board Foot because their dimensions yield different cubic measurements. For instance, 10"x10"x1" would produce 100 cubic inches, 14"x14"x1" would yield 196 cubic inches, and 16"x16"x1" results in 256 cubic inches. Only the specified dimensions of 12"x12"x1" align with the standard definition for a Board Foot.
