You will need 200 cubic feet.
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.
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.
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).
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!
It depends on the thickness and the density. One ton should be about 15 cubic feet when compacted, so it would cover 30 square feet 6 inches thick or 45 square feet 4 inches thick or 60 square feet 3 inches thick. It would make a driveway four inches thick, 9 feet wide and 5 feet long or a footpath 3 inches thick, three feet wide and 20 feet long.
You have given three dimensions; square feet has only two dimensions. Do you mean cubic feet?
the formula for figuring out asphalt is.. L x W x D x 110 / 9 / 2000 = tons of asphalt. Where: L = Length in feet W = Width in feet D = Depth in inches 110 = a average weight of a square foot asphalt 1 inch thick /9 = convert to square yards /2000 = convert weight to tons So.. 27707 x 3 x 110 / 9 / 2000 = 508 tons.
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.
1 yard topsoil covers 100 square feet to 3 inches, 200 square feet to 1.5 inches and 300 square feet to 1 inch.
One cubic yard covers 81 square feet 4 inches thick.
