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.
To calculate the amount of asphalt needed for an area of 8,388 square feet at a thickness of 2 inches, first convert the thickness to feet: 2 inches is approximately 0.167 feet. Multiply the area by the thickness: 8,388 sq ft × 0.167 ft = 1,399.596 cubic feet. Since asphalt weighs about 145 pounds per cubic foot, the total weight is approximately 202,000 pounds, or about 101 tons.
It isn't clear what exactly you want to calculate.
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.
To calculate the square footage of an 18x18 tile, you multiply the length by the width. Thus, 18 inches multiplied by 18 inches equals 324 square inches. To convert square inches to square feet, divide by 144 (since there are 144 square inches in a square foot). Therefore, an 18x18 tile covers 2.25 square feet.
To calculate the square yards (SQ YDS) of asphalt at 3 inches thick, you first need to convert the thickness from inches to feet, which is 0.25 feet. The volume of asphalt in cubic feet can then be calculated by multiplying the area in square feet by the thickness in feet. Since 1 square yard equals 9 square feet, you can use this conversion to determine the total area in square yards needed based on the total volume of asphalt required. For specific calculations, you would need the total volume in cubic feet or the area to be paved.
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.
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.
To estimate the amount of asphalt needed for 7,840 square feet, you first need to determine the thickness of the asphalt layer. Typically, a standard thickness for an asphalt surface is about 2 inches. Using this thickness, approximately 0.1 tons of asphalt is needed per square foot for 2 inches. Therefore, for 7,840 square feet, you would need around 784 tons of asphalt.
You have not said what substance you are using a ton of to cover the asphalt.
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.
To convert square inches to square yards, divide square inches by 1,296.
Square inches x 0.00694 = square feet
Multiply by 144.
To calculate the amount of asphalt needed for an area of 140 square feet at a thickness of 3 inches, first convert the thickness to feet (3 inches = 0.25 feet). Multiply the area by the thickness: 140 sq ft × 0.25 ft = 35 cubic feet. Since asphalt typically weighs about 145 pounds per cubic foot, you would need approximately 5,075 pounds of asphalt for your project.
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
