1350/depth of the concrete in feet
The answer depends on whether you mean 114 feet squared or a square 114 feet by 114 feet. The answer to the first scenario is 76 square yards of concrete. The answer to the second scenario is 8,664 square yards of concrete.
For 100 yards of concrete for your new driveway it is 2700 square feet.
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.
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.
divide by 9
37 yards of concrete is needed for a 3000 square feet 4 inches thick.
For 576 square feet at a depth of 4 inches, you will need 7.11 cubic yards.
Convert the measurement in square feet to square yards and the thickness in inches to yards. 3 feet = 1 yard 9 square feet = 1 square yard. : 1100 square feet = 1100/9 = 122.2222 sq yards 36 inches = 1 yard 5 inches = 5/36 = 0.13888 yards. The amount of concrete required = 122.2222 x 0.13888 = 16.975 cubic yards In practice, an order would be sent for 17 cubic yards of concrete.
30' x 20' (600 square feet) = 66.6 square yards.
720 square feet at the standard 4-inch depth requires 8.9 cubic yards.
