How to calculate how much soil you need?

To calculate the volume of soil, multiply the length of the area by its width and depth. Make sure to use the same units.

Length [x] * Width [x] * Depth [x] = Volume [x³]
Example: Calculate the volume of soil for an area with a length of 15 ft, width of 45 ft, and depth of 9 in.

8 in = 0.75 ft

Volume of soil = 15 ft * 45 ft * 0.75 ft

Volume of soil = 506.25 ft³
