### Cubic Yard Calculations

**Calculating Cubic Yards for Square / Rectangular Areas:**

Length(ft.) x Width(ft.) x Depth (in.) = "X"

"X" Divided by 324 = cubic yards.

**Calculating Cubic Yards for Circular Areas:**

Radius squared x 3.14 (Pi) x depth (all expressed in feet) = cubic feet divided by 27 = cubic yards.

NOTE: 1 cubic yard = 27 cubic feet (3'x3'x3')

Example: A 50-foot diameter circular area, 4 inches deep. NOTE: The radius is 1/2 of the diameter, so the calculation should be: 25' x 25' x 3.14 x .33 = 648 cubic feet divided by 27 = 24 cubic yards.
