You have not said what substance you are using a ton of to cover the asphalt.
The amount of square feet in a ton of asphalt will depend on the thickness of the asphalt. If the asphalt is three inches thick it will have to cover the area three times. The type of asphalt used is also a factor towards weight.
36 tonnes
As a rule of thumb, 0.112 tons of asphalt (2" thick) will cover 1 square yard or 9 square feet. Thus 1 tone of asphalt (2" thick) will cover 8.93 square yards or 80.36 square feet. ------------------------------- Another (possibly more accurate) way of doing this is to use standards 1 ton [long, UK] = 2240 pounds Density of compacted Asphalt = 147 pounds per cubic foot (1728 cubic inches) 12 inches times 12 inches times 2 inches = 288 cubic inches Thus the weight of 288 cubic inches of compacted asphalt will be (288/1728)* 147 = 24.5 pounds. Therefore a tone of asphalt will cover 2240/24.5 = 91.43 square feet to a depth of 2 inches.

40.5 sq ft
You will need 200 cubic feet.
One "yard" of dirt (meaning one cubic yard) contains 46,656 cubic inches. Spread 8 inches thick this will cover 5832 square inches or 40.5 square feet.
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!
540 square feet
About 162sf.
1 cubic yard covers 324 square feet per inch of thickness, divide 324 by thickness in inches to get coverage, i.e. 4 inches thick would cover 324/4=81 square feet, 36 inches thick would cover (you guessed it) 9 square feet.
