How many square feet is a yard of concrete?

Answer 1

A yard of concrete is a cubic yard and cannot be converted directly to square feet of coverage. You must first determine the depth or thickness that the concrete will be.

For instance, since 1 cubic yard equals 27 cubic feet, a 1 foot thick layer of concrete will cover 9 square yards of area. A 4 inch (1/3 foot) thick layer would cover 27 square feet of area.
