4 inches = 1/3 foot
Volume = 40-ft x 3-ft x 1/3-ft = 40 cubic feet
To determine how many cubic feet of concrete are needed, you first need to know the depth of the concrete slab. For example, if the slab is 6 inches thick, you would multiply 360 square feet by the thickness in feet (6 inches = 0.5 feet) to get 180 cubic feet of concrete required.
To convert square feet to cubic yards, you need to multiply by the height. Since the height is given in inches, you first need to convert it to feet (4 inches = 0.33 feet). Then, you can calculate: 460 sq ft * 0.33 ft = 151.8 cubic feet. Finally, you can convert cubic feet to cubic yards (1 cubic yard = 27 cubic feet), so 151.8 cubic feet / 27 = 5.62 cubic yards in 460 square feet at 4 inches thick.
There are 1728 cubic inches in 1 cubic foot. Therefore, 5 cubic feet would be equivalent to 8640 cubic inches.
There are 27 cubic feet in 4800 cubic inches. This conversion is based on the fact that 1 cubic foot is equal to 1728 cubic inches. Therefore, 4800 cubic inches equals 2.78 cubic feet.
There are 9 square yards in a cubic yard at a thickness of 3 inches. This is because there are 9 square feet in a square yard and 36 cubic feet in a cubic yard, so the area is 9 square yards if the thickness is 3 inches.
137.5 cubic feet or 5.09 cubic yards.
625 times 0.5 = 312.5 cubic feet will be needed
how many cubic feet in a yard of concret
A 9x9 foot slab 4 inches thick requires a minimum of 1 cubic yard. If you go to 6 inches thick you will need 1.5 cubic yards.
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.
1 cubic yard will cover ~90 sq feet
(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
Apples and oranges. Without knowing how thick the 450 sq. ft. area is or how thick you want it to be you can't convert to cubic yards. A cubic yard has 27 cubic feet. One square foot 3 inches thick would be 1/4 cubic feet. 4 sq. ft. 3 inches thick would be 1 cubic foot. 450 sq. ft. 3 inches thick is 112 1/2 cubic feet or just a bit over 4 cubic yards. 450 sq. ft. 4 inches thick is 150 cubic feet or 5 1/2 cubic yards.

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.
