You need to specify the slab's width and the length as well.

It depends upon how thick you want the concrete. For example, if you want the concrete to be 6 inches thick, then you will need 200 cubic feet. There are 27 cubic feet per cubic yard; so divide the 200 cubic feet by 27 to get 7.4 cubic yards.
A cubic yard is 46,656 cubic inches. Spread to a thicknes of 5 inches, a cubic yard of concrete covers 9332.1 square inches, which is 64.8 square feet.
To measure the concrete needed for a circular pad:-- Decide how thick (deep) the pad is to be. If it's in inches, divide by 12 for thickness in feet.-- Measure either the circumference or the diameter of the circle, in feet.-- If you measured the circumference, then the cubic yds of concrete needed is(0.00295) x (circumference) x (circumference, again) x (thickness) ... all in feet-- If you measured the diameter, then the cubic yds of concrete needed is(0.0291) x (diameter) x (diameter, again) x (thickness) ... all in feet

To calculate the amount of concrete needed for a slab measuring 60 inches by 60 inches with a thickness of 4 inches, first convert the dimensions to feet: 60 inches equals 5 feet, and 4 inches equals 0.33 feet. The volume of the slab is then calculated as length × width × thickness, which is 5 ft × 5 ft × 0.33 ft = 8.25 cubic feet. To convert this to cubic yards, divide by 27 (since there are 27 cubic feet in a cubic yard), resulting in approximately 0.31 cubic yards of concrete needed.
625 times 0.5 = 312.5 cubic feet will be needed

(3.5/12) x 120 = (.2917) x 120 = 35.004 Cubic Feet Concrete is sold by the cubic yard. 35.004 cubic feet = 1.3 cubic yards

9x12 feet at 4 inches deep: 1.3 cubic yards.

To calculate the amount of concrete needed for a slab measuring 10 feet by 14 feet and 4 inches thick, first convert the thickness to feet: 4 inches is approximately 0.33 feet. The volume in cubic feet is then calculated as 10' x 14' x 0.33' = 46.2 cubic feet. To convert this to cubic yards (since concrete is often sold by the cubic yard), divide by 27: 46.2 cubic feet ÷ 27 = approximately 1.71 cubic yards. Therefore, you would need about 1.71 cubic yards of concrete for the slab.
4300 x .66 * = 2838 cubic feet / 27 = 105.11 cubic yards. ( *.66 = 8" )
A 10-foot round slab at 4 inches requires 1 cubic yard.
