20 ft x 12 ft 1 inch is a measure of area (in 2-D space) while a cubic yard is a measure of volume (in 3-D space). The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid.
How many cubic yards in an 12 foot diameter circle with a 4 inch thickness?
3.7
1 inch = 1/12 foot27 cubic feet = 1 cubic yardVolume = 1,500 x 1/12 = 125 cubic feet = 417/27 cubic yards (rounded, that's 4.63)
1 inch = 1/12 foot2 cubic yards = 54 cubic feetVolume = (area) x (depth)54 = A x 1/12A = 54 x 12 = 648 square feet
500 sq ft X 1/12 ft / 27 cubic ft./cubic yard = 1.5 cubic yards

You would need approximately 2.5 cubic yards of gravel to cover a 12' by 15' area at a depth of 2 inches.
49 ft * 12 ft * 12 in = 49 ft * 12 ft * 1 ft = 588 cubic feet=588/27 cubic yards = 21.77... cubic yards.49 ft * 12 ft * 12 in = 49 ft * 12 ft * 1 ft = 588 cubic feet=588/27 cubic yards = 21.77... cubic yards.49 ft * 12 ft * 12 in = 49 ft * 12 ft * 1 ft = 588 cubic feet=588/27 cubic yards = 21.77... cubic yards.49 ft * 12 ft * 12 in = 49 ft * 12 ft * 1 ft = 588 cubic feet=588/27 cubic yards = 21.77... cubic yards.
Cubic inch is 1 inch x 1 inch x 1 inch There are 12 inches in a foot, so 1 cubic foot = 12 x 12 x 12 = 1728 cubic inches. Hence a cubic foot is 1728 times bigger than a cubic inch
72 cubic yards
