To calculate the amount of Quikrete needed for a slab measuring 5 feet by 8 feet, you first determine the volume in cubic feet. Assuming a standard thickness of 4 inches (0.33 feet), the volume would be 5 ft x 8 ft x 0.33 ft = 13.2 cubic feet. Quikrete typically comes in 60 lb or 80 lb bags, with each 60 lb bag covering about 0.45 cubic feet and each 80 lb bag covering about 0.6 cubic feet. You would need approximately 30 bags of 60 lb Quikrete or about 22 bags of 80 lb Quikrete to complete the slab.
