1 cubic yard = 27 cubic feet
6 inches = 1/2 foot
Volume = 7,211 x 1/2 = 3,605.5 cubic feet = 133.537 cubic yards (rounded)
1350/depth of the concrete in feet
If the depth is two feet, the minimum yards needed is 74.07.
1 cubic yard of concrete fills 27/depth in feet square feet.The number of cubic yards you need is(length of the pad in feet) x (width of the pad in feet) x (depth of the pad in inches)/324
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.
For 576 square feet at a depth of 4 inches, you will need 7.11 cubic yards.
19.55
720 square feet at the standard 4-inch depth requires 8.9 cubic yards.
To calculate the square footage covered by 4 yards of concrete at a depth of 4 inches, first convert the depth to feet (4 inches = 4/12 = 1/3 feet). Then, calculate the volume in cubic feet: 4 yards is 4 x 27 = 108 cubic feet. Finally, divide the volume by the depth: 108 cubic feet / (1/3 feet) = 324 square feet. Therefore, 4 yards of concrete at 4 inches deep covers 324 square feet.
For a 4-inch depth you will need 7.41 cubic yards.
If your pour to a standard 4-inch depth, you will need 3.54 Cubic Yards.
It depends on how deep it is. Multiply 3300 by the depth (in feet) and divide by 27
If you use a standard 4-inch depth, you will need at least 8.9 cubic yards.
