Measures of Volume are those measures which serve to estimate extent considered under three dimensions; viz., length, breadth, and thickness. TABLE. 1728 cubic inches (cu. in.) = 1 cubic foot...... cu. ft. NOTE.-Lumber is measured by board measure, whose unit is a board foot, 1 ft. long, 1 ft. wiḍe, and 1 in. thick, or of a cubic foot. All kinds of sawed timber, boards, planks, and joists are generally measured by this measure. But hewn and round timber are measured by cubic measure. ORAL EXERCISES. 1.
