How much soil does it take to build a berm 3ft x 20 ft?

To calculate the volume of soil needed to build a berm that is 3 feet high and 20 feet long, you need to determine the cross-sectional area. Assuming a width of 1 foot for simplicity, the volume would be 3 ft (height) x 20 ft (length) x 1 ft (width) = 60 cubic feet. Therefore, it would take 60 cubic feet of soil to build the berm. Adjust the width accordingly if it differs from 1 foot for a more accurate calculation.
