400 sq ft
54 sq ft per ton @ 3"
400/54=7.4 tons
To convert square inches to square yards, divide square inches by 1,296.

A three-dimensional box is measured in cubic inches. A two dimensional square is measured in square inches. For a box, multiply length of the three sides in inches. For a square, muliply the two sides.
The volume of that prism would be 224 square inches. To calculate this you do:Multiply base times height (width in your case), this equattion is 7x8=56. Now you have your areaNext multiply the area (which was 56 square inches) by the depth (4 square inches). 56x4=224. Your volume is now 224 square inches (or inches squared)
Multiply the two numbers together 6 ins x 9 ins = 54 sq. ins. ( Square inches ) Done!!!!!
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.
You have not said what substance you are using a ton of to cover the asphalt.
Calculate the volume of mix needed by multiplying 20x20x9. This gives cubic inches. Then divide that answer by 144 cubic inches per cubic foot, and you have the volume in cubic feet. A cubic foot of asphalt is a different weight depending on the weight of the rock in contains, but let's 158 pound of asphalt hotmix per cubic foot. Multiply the volume in cubic feet, above, by 158lbs, and you have the weight of mix per 20x20x9. Divide the answer by 2000 to convert to tons. Divide the tonnage by the weight per cubic feet calculated above in the second paragraph.
To convert square inches to square yards, divide square inches by 1,296.
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.
Square inches x 0.00694 = square feet
Multiply by 144.
It covers an area of 21.62 square centimeters. (1.85 inches by 1.81 inches, covering an area of 3.35 square inches)
Inches is a linear measurement and square feet is an area.It is an apples and oranges things.BUT, if you want square inches to square feet, use this:1 square inches = 0.00694444444 square feet

70sq. in.
You will need 200 cubic feet.
