None.
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
