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.
