## Volume of a **Pile of Gravel** or Sand

Example Calculation: Suppose a **pile of gravel** is in the shape of a cone with a height of 24 inches and a diameter of 40 inches. The top of the cone is moderately rounded. First, find the basic conical volume in cubic inches by using the formula π D²H/12. This gives you. π (40)² (24)/12 = 10053 cubic inches. Next, convert this to cubic yards ...
