Calculating cubic ft - Office Equipment & Supplies

In order to calculate cubic feet you must multiply the LxWxH (where L=length, W=width and H=height or depth) making sure all three numbers are in feet. For example: a box 3' long by 2' wide by 1.5' high would contain 9 cubic feet of space. (3x2x1.5). If one or more of the measurements is in inches then you must convert it to feet or the others to inches. If all three measurements are in inches multiply them and then divide your answer by 1728 to give cubic feet because their are 1728 cubic inches in a cubic foot. (12x12x12). For example the same problem above in inches would be: 36x24x18=15,552cubic inches. Divide 15,552 by 1728 = 9 cubic feet
