To calculate the volume of concrete needed for a slab, you can use the formula: Volume = Area × Thickness. First, convert the thickness from inches to feet: 4 inches is 1/3 feet. Then, multiply the area (256 square feet) by the thickness (1/3 feet): 256 × (1/3) = approximately 85.33 cubic feet of concrete is needed for the slab.

A 10-foot round slab at 4 inches requires 1 cubic yard.
9x12 feet at 4 inches deep: 1.3 cubic yards.
To calculate the amount of concrete needed for a 12x30 slab, you first determine the area by multiplying the length (30 feet) by the width (12 feet), which equals 360 square feet. If the slab is to be 4 inches thick, convert the thickness to feet (4 inches = 1/3 feet) and then calculate the volume: 360 square feet x 1/3 feet = 120 cubic feet. Since there are 27 cubic feet in a cubic yard, divide 120 by 27 to find that approximately 4.44 cubic yards of concrete is needed.
To calculate the amount of concrete needed for a slab measuring 10 feet by 14 feet and 4 inches thick, first convert the thickness to feet: 4 inches is approximately 0.33 feet. The volume in cubic feet is then calculated as 10' x 14' x 0.33' = 46.2 cubic feet. To convert this to cubic yards (since concrete is often sold by the cubic yard), divide by 27: 46.2 cubic feet ÷ 27 = approximately 1.71 cubic yards. Therefore, you would need about 1.71 cubic yards of concrete for the slab.
A cubic foot of concrete weighs ABOUT 150 pounds. 4 feet by 12 feet by 4 feet is 192 cubic feet. If you meant 4 feet by 12 feet by 4 INCHES, that would be 16 cubic feet.
