I have a pile of dirt that is 200ft long, 40ft wide, and 25ft high. How do I figure out how many cubic yards?
Thanks Mark

Hi Mark,

Since all your measurements are in feet and you want the volume in cubic yards you should change the measurements to yards. There are 3 feet in a yard so

200 ft = 200/3 yards
40 ft = 40/3 yards and
25 ft = 25/3 yards.

The volume of a rectangular solid is the length times the width times the height so the volume of your pile of dirt is

200/3 x 40/3 x 25/3 = 7407 cubic yards.
