### 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.
