Concrete is a mixture of cement , sand, gravel and water. A cubic yard of concrete is 3' x 3' x 3' . That's 3x3=9x3=27 . 27 cubic feet = 1 cubic yard . So it's 27 feet divided by 3 inches equals 108 sq ft!
1 sq. feet = 144 sq. inchesSo,392 sq. feet = 144 * 392 sq inches = 56448 sq. inchesVolume of cement needed = 56448 sq inches * 4 inch = 225792 cubic inches225792 cubic inches = 1568 cubic feet
You would need 31, 80 pound bags to cover 1 cubic yard at 4 inches deep. If you would like the depth to be 6 inches, 45 bags would be needed.
