Volume of concrete needed = 4 x 12 x 1/3 = 4 x 4 = 16 cubic feet
A cubic yard of concrete covers an area of 81 square feet when poured at a thickness of 4 inches. This is calculated by dividing the total volume of the cubic yard (27 cubic feet) by the thickness in feet (1/3 foot for 4 inches), resulting in 27 ÷ (1/3) = 81 square feet.

You will need 200 cubic feet.

how many cubic feet in a yard of concret
12.5 cubic feet. Assuming you meant 4 INCHES thick..
If it is 4 inches deep/thick, 2 cubic yards. If it is 6 inches deep/thick, 3 cubic yards.
To calculate the volume of concrete needed for a 12'x16' area that is 3 inches thick, first convert the thickness to feet: 3 inches is 0.25 feet. Then, multiply the area by the thickness: (12 \times 16 \times 0.25 = 48) cubic feet. Therefore, 48 cubic feet of concrete is required for the project.
you can do the math: LXWXD DIVIDED BY 27
625 times 0.5 = 312.5 cubic feet will be needed
A 9x9 foot slab 4 inches thick requires a minimum of 1 cubic yard. If you go to 6 inches thick you will need 1.5 cubic yards.
To calculate the volume of concrete needed for a slab that is 12 feet by 20 feet and 4 inches thick, first convert the thickness to feet: 4 inches is equal to 1/3 foot. The volume in cubic feet is then calculated as follows: 12 ft × 20 ft × (1/3 ft) = 80 cubic feet. Therefore, you will need 80 cubic feet of concrete for the slab.
387 cubic feet. This is because 43x18x0.5 (as six inches is 1/2 of a foot) =387.
To calculate the volume of concrete needed for a slab that measures 74 inches long, 48 inches wide, and 4 inches thick, first convert the dimensions to feet: 74 inches = 6.17 feet, 48 inches = 4 feet, and 4 inches = 0.33 feet. Then, multiply the dimensions: 6.17 ft × 4 ft × 0.33 ft = approximately 8.16 cubic feet. Therefore, you will need about 8.16 cubic feet of concrete for the slab.
