151/9 cubic yards for every 12 inches thick
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.
1.8 Cubic yards of concrete is 48.6 cubic feet. Each 80lb bag of concrete is .6 cubic feet. Therefore, you would need 81 bags. Hope that helps. GEO
Assuming you need a slab 25 feet x 32 feet x 4" you would need 10 yards of concrete. 25 x 32 x .33 / 27 = 9.7 cubic yards
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)
25856 / 27 = 958 yards of concrete @ $75 per yard = $71,850
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.
A yard (of dirt or concrete) is a volume of 1 cubic yard (1 yd)³, as the cubic is assumed in this context. Assuming a circle 7 feet across (diameter), then the radius is 3.5 feet = 1.16667 yards, and 8 inches = 0.2222 yards. So the volume of this is about 0.95 cubic yards. In concrete jargon it would be 0.95 yards.
how may yards of concrete are needed for a floor 24 x 25 feet?
2.2 Yards
you would need 37.33 yards of concrete or 38 to be safe
