Question from BELINDA:

I need to fill an area of 30,000 square feet with dirt that is 18" in height. How many cubic yards of dirt do I need to do this?

Hi Belinda,

You can use our volume calculator to do this. You have an area of 30,000 square feet so it might be 30 feet by 1000 feet and thus you can use a length of 1000 feet, a width of 30 feet and a depth of 18 inches.
