Gravel Calculator - calculate how much gravel you need
Let H be the height of the pile. All of these measurements need to be in yards. Let R = W / 2 then the volume of the pile in cubic yards is . V = 1 / 2 W H S + 1 / 3 π R 2 H. where π is approximately 3.14. If you decide to measure a pile and use this expression let me know what measurements you get.
