A 9x9 foot slab 4 inches thick requires a minimum of 1 cubic yard. If you go to 6 inches thick you will need 1.5 cubic yards.
One yard will cover 81 square feet 4 inches thick, So 81x40=3,240 square feet if spread 4 inches thick. 36/4=9, 9x3x3=81, 81x40=3,240 If you want it 6 inches thick 36/6=6, 6x3x3=54, So one yard will cover 54 square feet 6 inches thick, And 54x40=2,160 square feet If spread 6 inches thick! Now this is spreading it on thick/DEEP!
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.
1.2 (cubic feet) = 2073.6 cubic inches FYI: Google "convert 1.2 cubic feet to cubic inches"

If the 29 inches by 15 inches object is 1 inch thick, it has a volume of approximately 0.252 cubic feet (3.02/12).
36x36x36 inches or 3x3x3 feet or 27 cubic feet. If applied a foot thick, it will cover 27 square feet; 6 inches thick = 54 square feet (e.g.: an area 9 feet by 6 feet); 3 inches thick = 81 square feet (e.g.: an area 9 feet by 9 feet).
