Measure the length of the cylinder with a measuring tape. Multiply this measurement by the result obtained in the above step. (Example: if the length of your cylinder is 24 inches, then 24 x 113.04 = 2712.96 square inches) Divide the square inch volume of the cylinder by 1728 to get the cubic feet of the cylinder.
Your answer will be the volume of the box expressed in a unit of volume called cubic inches.. What To Look For: Suppose your box was 6 inches high, 5 inches wide, and 9 inches long. You would multiply 6 times 5 times 9. Your answer would be 270.
