30' x 20' (600 square feet) = 66.6 square yards.
Square yards x 9 = square feet.
There are 3 feet to a yard, and 9 square feet to a square yard. Multiply yards by 3 to get feet. Multiply square yards by 9 to get square feet.
152 square yards = 1,368 square feet.
180 square yards = 1,620 square feet.
30' x 20' (600 square feet) = 66.6 square yards.
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.
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.
1350/depth of the concrete in feet
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.
As long as you mean square yards, then: 1 square yard = 9 square feet 4077 square feet / 9 square feet per square yard = 453 square yards
divide by 9
For 576 square feet at a depth of 4 inches, you will need 7.11 cubic yards.
The area of that slab is (60 x 20) = 1,200 square feet = 1331/3 square yards.But that doesn't tell you how much concrete you'll need in order to pour it.What you really want to know is the cubic yards of volume required. That'swhat the concrete guys are talking about when thery say "yards" of concrete.1 cubic yard = 27 cubic feetVolume = (length) x (width) x (height) = (60 x 20 x 1/2) = 600 cubic feet = 222/9 cubic yards.( 22.22222... )
720 square feet at the standard 4-inch depth requires 8.9 cubic yards.
18' x 16' (288 square feet) = 32 square yards.
9 sq. ft. in a sq. yd.
