To calculate the volume of concrete needed for a slab that is 30 feet by 30 feet and 4 inches thick, first convert the thickness to feet: 4 inches is 1/3 of a foot. Then, multiply the dimensions: 30 ft x 30 ft x (1/3 ft) = 300 cubic feet. To convert cubic feet to cubic yards, divide by 27 (since there are 27 cubic feet in a cubic yard): 300 / 27 ≈ 11.11 cubic yards. Therefore, you will need approximately 11.11 yards of concrete.
