A yard of concrete is 27 cubic ft. Your measurements, if in feet, represents 480 cubic ft. Dividing this by 27 results in 17.78 yards.
6 feet or 36 inches.
you would need 37.33 yards of concrete or 38 to be safe
If it is the same as concrete it will cover 162 square feet. concrete covers 81 square feet by 4" deep
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.
how may yards of concrete are needed for a floor 24 x 25 feet?
55.56 cubic yards.
39.1116 cubic yards
90
Yards are for measuring length not volume. Cubic yards required will be as follows: 1 cubic yard = 3 feet x 3 feet x 3 feet = 27 cubic feet Your concrete pad is 30ft x 40ft x 0.3333ft (4 inches assumed) = 400 cubic feet 400 divided by 27 = 14.8148 cubic yards required
20 feet x 20 ft x .3333 ft = 133.33 cubic feet / 27 cubic feet per yard = 4.94 cubic yards
about 17 yards of concrete (it's sold by the cubic yard)
For a 4-inch thick slab, you will need at least 9.48 Cubic Yards.
about 26.4 is the volume i think.......
1350/depth of the concrete in feet
one (1) cubic yard of concrete four inches thick will cover 80 sq. feet. 85 yards x 81 = 6885 sq. feet.
