To calculate the amount of concrete needed, first convert all measurements to feet. The volume of concrete required can be found using the formula for volume: length × width × height. For a slab that is 62 feet long, 30 feet wide, and 5 inches thick (which is 5/12 feet), the volume is 62 × 30 × (5/12) = 155 cubic feet. Therefore, you will need approximately 155 cubic feet of concrete.

10 80# bags will fill about 6 cubic feet, so 375 bags should fill 225 cubic feet (30 x 30 x 0.25).ANS 2 -At least in my area, it would be much cheaper ordering this to be delivered by a concrete truck.An 80 lb. bag of concrete is 2/3 of a cubic ft. of concrete. 3 bags is 2 cu. ft. So for 225 cu.ft. youll need 338 bags of concrete.
