ONE I THINK, SINCE THERE ARE 27 CUBIC FEET IN A CUBIC YARD OF CONCRETE (WHICH MEASURES 3 FEET BY 3 FEET BY 3 FEET).

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.
A yard of concrete is a cubic yard and cannot be converted directly to square feet of coverage. You must first determine the depth or thickness that the concrete will be. For instance, since 1 cubic yard equals 27 cubic feet, a 1 foot thick layer of concrete will cover 9 square yards of area. A 4 inch (1/3 foot) thick layer would cover 27 square feet of area.
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.
(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
how many cubic feet in a yard of concret
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.
1 "yard" of concrete actually = 1 cubic yard = 27 cubic feet27 = (2/3) x81 = 2 xx = 40.5 square feet
How thick? Gotta have thickness to calculate cubic yards.

1 cubic yard = 27 cubic feet700 square feet x 1/2 foot = 350 cubic feet = 1226/27 cubic yards(12.963 cubic yards, rounded)
