To determine the amount of cement needed for a concrete slab covering 3,200 square feet, you first need to decide on the thickness of the slab. For example, a typical thickness is 4 inches (0.33 feet). The volume of concrete required would be 3,200 sq ft × 0.33 ft = 1,056 cubic feet. Since concrete is typically composed of about 10-15% cement by volume, you would need approximately 106 to 158 cubic feet of cement, which translates to roughly 3.9 to 5.9 cubic yards of cement.
A 60-pound bag of concrete mix typically yields about 0.45 cubic feet of concrete. To convert this to square feet, you need to know the thickness of the slab you plan to pour. For example, if you're pouring a 4-inch thick slab, the 60-pound bag would cover approximately 13.5 square feet.
144 square feet. Multiply length by width - the result is the area in square feet.
To determine the amount of concrete needed for a 30 x 12 area, you first need to calculate the area, which is 30 feet multiplied by 12 feet, resulting in 360 square feet. If you're pouring a standard thickness of 4 inches (0.33 feet), you would multiply the area by the thickness: 360 square feet x 0.33 feet = 118.8 cubic feet. To convert cubic feet to cubic yards (since concrete is typically sold by the cubic yard), divide by 27, resulting in approximately 4.4 cubic yards of concrete required.
12.30 cubic yards
Flatwork = Total square feet (L x W) x .33 (4 ") / 27 = yards concrete
using epoxy paint to do a concrete floor need to know how much square feet it is how do i calculate the square footage?
80 ft x 120 ft = 9600 ft2 of concrete

To determine how many cubic feet of concrete are needed, you first need to know the depth of the concrete slab. For example, if the slab is 6 inches thick, you would multiply 360 square feet by the thickness in feet (6 inches = 0.5 feet) to get 180 cubic feet of concrete required.
For 576 square feet at a depth of 4 inches, you will need 7.11 cubic yards.
A few extra square feet of the square feet you need.
To calculate the amount of concrete needed to cover a driveway that is 9 feet wide and 150 feet long, you first find the area by multiplying the width by the length: 9 feet × 150 feet = 1,350 square feet. The depth of the concrete layer is also needed to determine the volume. For example, if you want a thickness of 4 inches (0.33 feet), the volume would be 1,350 square feet × 0.33 feet = 445.5 cubic feet.
720 square feet at the standard 4-inch depth requires 8.9 cubic yards.
1 cubic yard of concrete fills 27/depth in feet square feet.The number of cubic yards you need is(length of the pad in feet) x (width of the pad in feet) x (depth of the pad in inches)/324
