Multiply the rise (5") by .66 (2/3). This equals 3.3. Add the 3.3 to the 25". This now gives us our revised height measurement (28.3) and the three dimensions we use for multiplication: 30 x 30 x 28.3 = 25,470 cubic inches. For cubic feet, divide cubic inches by 1728. Our cu. in. number 25,470 divided by 1728 = 14.74 cu. ft.
