The best way to approach this problem is to make all of these units consistent. Since you want your result to be in cubic yards, let's make all the linear dimensions yards as well. So since 1 yard = 3 feet = 36 inches, you have 60 ft/3 = 20 yards by 80 ft/3 = 26.667 (approx) yards by 5 in/36 = .13889 (approx) yards. Now multiply your constants together: 20 * 26.667 * .13889 = approximately 74 cubic yards of concrete.
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.
You need to specify the slab's width and the length as well.
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.

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.
625 times 0.5 = 312.5 cubic feet will be needed

4300 x .66 * = 2838 cubic feet / 27 = 105.11 cubic yards. ( *.66 = 8" )
To calculate the amount of concrete needed for a 500 square foot area at 4 inches thick, first convert the thickness to feet: 4 inches is equal to 1/3 foot. Then, multiply the area by the thickness: 500 sq ft x (1/3 ft) = approximately 166.67 cubic feet. Since concrete is typically ordered in cubic yards, divide this by 27 (the number of cubic feet in a cubic yard), which gives you about 6.17 cubic yards of concrete 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
A 10-foot round slab at 4 inches requires 1 cubic yard.
If it is 4 inches deep/thick, 2 cubic yards. If it is 6 inches deep/thick, 3 cubic yards.
To calculate the volume of concrete needed for a 12'x16' area that is 3 inches thick, first convert the thickness to feet: 3 inches is 0.25 feet. Then, multiply the area by the thickness: (12 \times 16 \times 0.25 = 48) cubic feet. Therefore, 48 cubic feet of concrete is required for the project.
