Which statement is true regarding a "board foot"?

A board foot is a volume measurement of lumber that is specifically defined as a board or plank that measures 1 inch thick, 1 inch wide, and 12 inches long. This definition is the standard used in the lumber industry to describe the volume of wood. A single board foot is equivalent to 144 cubic inches.

Understanding this definition is crucial for anyone working in lumber sales or construction, as it facilitates the accurate calculation of lumber quantity needed for projects. The significance of this measurement lies in its practicality for purchasing, selling, and estimating wood usage in various applications, from building to crafting.

The other statements do not accurately represent the definition of a board foot. The second statement describes a different volume of wood but does not adhere to the standard definition. The third statement incorrectly suggests that a board foot correlates to the weight of lumber, which is not the case; weight can vary based on the type and moisture content of the wood. The fourth statement mistakenly connects the term to the height of a tree, which is unrelated to the volumetric measurement of lumber. Therefore, the true definition of a board foot clearly aligns with the first statement provided.
