Yards of concrete

[MidgeA@aol.com]

I need to know how much concrete (in yards) I need for an area: 12 ft x 8 ft x 4inches.

First convert the 4 inches into feet (4 inches divided by 12 inches in a foot) --- 4/12=.3333 ft

Multiply 12 ft x 8 ft x .3333 ft = 32 cubic feet

A cubic yard has 27 cubic feet (3 ft x 3 ft x 3 ft), so divide 32 cubic feet by 27 cubic feet --- 32/27=1.185 cubic yards
