You convert everything to compatible units. Then you multiply area x depth. I suggest you convert the depth to feet; in that case, the answer will be in cubic feet.
To calculate the amount of sand needed, first convert the depth from inches to feet: 2 inches is about 0.167 feet. Then, multiply the area by the depth: 452 square feet × 0.167 feet = approximately 75.5 cubic feet of sand needed.
Calculate attic square footage, calculate how much free area you need by dividing the attic square footage by 300. Convert the square feet needed to inches. Split the amount of free area needed equally between the intake and the exhaust. Divide that by 60, for how many vents you'll need.
To convert square inches to square yards, divide square inches by 1,296.
Square inches x 0.00694 = square feet
To find the least amount of cardboard needed to make a box measuring 8 inches by 12 inches by 12 inches, we need to calculate the surface area. The surface area (A) of a rectangular box is given by the formula (A = 2(lw + lh + wh)), where (l), (w), and (h) are the length, width, and height, respectively. Substituting in the dimensions, (A = 2(8 \times 12 + 8 \times 12 + 12 \times 12) = 2(96 + 96 + 144) = 2(336) = 672) square inches. Thus, the least amount of cardboard needed is 672 square inches.
Multiply by 144.
The amount of space inside a square is called the area of a square. To calculate the area of a square, take the length of one side squared.For example, if a square has one side of 4 inches:area = 4 x 4area = 16 square inches

To calculate the amount of top soil needed, measure the length and width of the area to be covered in feet. Multiply the length by the width to get the square footage. Then, determine how deep you want the topsoil to be and convert that to feet. Multiply the square footage by the depth to get the volume of topsoil needed in cubic feet.
To calculate the amount of drywall needed for a project, measure the height and width of the walls or ceilings to be covered. Multiply the height by the width to get the square footage. Subtract the area of any doors or windows. Divide the total square footage by the size of the drywall sheets (usually 4'x8') to determine how many sheets are needed.
