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.
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.
(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
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.
39.1116 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)
A cubic foot is 12" thick 12" wide and 12" deep. .45 cubic feet per 60# bag of concrete
