About lumber volume units
A board foot is the volume of a board 1 ft long, 1 ft wide and 1 inch thick (144 in³). Hardwood is sold by the board foot; firewood by the cord (128 ft³ of stacked wood, including air gaps). Note that lumber is priced on nominal dimensions — a “2×4” actually measures 1½ × 3½ in.
