If you have a 10 ft x 10 ft slab it would need a 1.3 yard of concrete, this is equal to 10 feet by 10 feet by .33 feet/ 27.Since the average slab measures 4 inches deep compute the depth that you intend to use.f you have a 10 ft x 10 ft slab it would need a 1.3 yard of concrete, this is equal to 10 feet by 10 feet by .33 feet/ 27.
