roughly 240 square feet. Formula for figuring yardage is: (Width X Length X thickness)/27= cubic yardage of concrete. Just reverse the formula to solve for Width X Length or Square Feet. CY X 27 divided by thickness = square footage
How many square yards in a 20x18 feet 3 inches thick
16 * 20 = 320 sq ft. at 4" thick concrete will cover 80 sq ft. 320 / 80 = 4 yards.
Assuming 4 inches thick, about 65.19 yards or rounded 66 yards (always round up to nearest yard).
about 26.4 is the volume i think.......
concrete is sold in cubic yards in the united states. I hope you are using a 1/4 inch diameter reinforce mesh. 1680 / 81 = 20.74 cubic yards without subtracting the mesh volume.
1000 square feet/9 = 111.1 square yards of concrete 6 inches thick. This is the same as 111.1/4.5 = 24.7 cubic yards of concrete.
How thick? Gotta have thickness to calculate cubic yards.
39.1116 cubic yards
One square yard is nine square feet, so 27 square feet is equivalent to 3 square yards. So 3 yards of concrete will cover 27 square feet.
It should be a little over 19 yards.
For a 4-inch thick slab, you will need at least 9.48 Cubic Yards.
