How much concrete for a slab 12 ft By 20 ft 4 inches thick?

Answer 1

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.
