How many square feet is a yard of concrete?
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.
How much area will 4 cubic yards take up?
4 cubic yards is 108 cubic feet.If you were pouring a concrete sidewalk that was 6" thick and 4 ' wide.it would be 54' long.If you wanted to topdress a lawn with loam, guessing an average coverage of 4".It will cover an area about about 16' x 20'With an average coverage of 2" it will do an area roughly 32' x 32'.
How many yards of concrete will cover 250 square feet at 3 inches thick?
Our area is 250 ft2 so 250 ft3 would cover the area with cement a foot deep. We only need 3 inches (1/4 of a foot) so we divide 250ft3 by 4 to get our answer: 62.5 cubic feet.However, the question asks for "yards of concrete" so we need to convert cubic feet into cubic yards as follows:One cubic yard = 3ft x 3ft x 3ft = 27 ft3Dividing our cubic foot answer of 62.5 by 27 we get our answer in cubic yards:62.5/27 =2.3148148 yd3 (the 148 repeats)
How many square yards of concrete is in a 16' x 20' area at 4 inches thick?
16 * 20 = 320 sq ft. at 4" thick concrete will cover 80 sq ft. 320 / 80 = 4 yards.
How much concrete for 10ftx10ft square area?
