To determine how many 80-pound bags of concrete are needed to fill an 8-foot by 8-foot by 5-inch thick slab, first calculate the volume of the slab. The volume is 8 ft x 8 ft x (5/12) ft = 26.67 cubic feet. An 80-pound bag of concrete typically yields about 0.6 cubic feet, so you would need approximately 45 bags (26.67 cubic feet ÷ 0.6 cubic feet per bag).

How many bags of concrete will you need for 30 ft 30ft 3in thick?

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.


How many bags of concrete will i need to fill a five gallon bucket?

To determine how many bags of concrete you need to fill a five-gallon bucket, first calculate the volume of the bucket. A five-gallon bucket holds about 0.67 cubic feet. If you're using a standard 60-pound bag of concrete, which typically yields about 0.45 cubic feet, you would need approximately 1.5 bags to fill the bucket. Always check the specific yield of the concrete mix you are using for the most accurate calculation.


How many concrete bags for a 10x10x2?

To calculate the number of concrete bags needed for a 10x10x2 foot slab, first find the volume in cubic feet: 10 x 10 x 2 = 200 cubic feet. A standard 80-pound bag of concrete typically covers about 0.6 cubic feet. Therefore, you would need approximately 334 bags (200 ÷ 0.6 ≈ 333.33) of concrete to fill that volume.

How many 80 pound bags of concrete will it take to fill a 55 gallon drum?

To determine how many 80-pound bags of concrete are needed to fill a 55-gallon drum, first calculate the volume of the drum. A 55-gallon drum holds about 7.4 cubic feet (since 1 gallon is approximately 0.133 cubic feet). An 80-pound bag of concrete typically yields about 0.6 cubic feet. Therefore, you would need approximately 12 to 13 bags of concrete to fill the drum.


How many 80lb bags of concrete are in a yard?

There are approximately 27 cubic feet in a cubic yard, and an 80-pound bag of concrete typically yields about 0.6 cubic feet. Therefore, to fill one cubic yard, you would need about 45 bags of 80-pound concrete.


How many 80 lbs bags of concrete to fill 30 gallon drum?

To fill a 30-gallon drum with concrete, you would need approximately 12 bags of 80-pound concrete. This is based on the fact that one 80-pound bag of concrete yields about 0.6 cubic feet, and a 30-gallon drum holds about 4 cubic feet. Therefore, dividing 4 cubic feet by 0.6 cubic feet per bag gives you roughly 6.67 bags, but accounting for the weight and settling, it's safer to estimate around 12 bags.
