To calculate the volume of the space, multiply the dimensions: 18 ft × 18 ft × 8 ft = 2,592 cubic feet. An 80 lb bag of Quikrete typically fills about 0.6 cubic feet. Therefore, to find the number of bags needed, divide the total volume by the volume per bag: 2,592 cubic feet ÷ 0.6 cubic feet/bag = 4,320 bags. You will need approximately 4,320 bags of Quikrete to fill the space.

That would depend on the density of the bags of topsoil.
1 50kg bag fill about 2 cubic f. so for 102cu.f. you'll need 51 bags

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.

To determine how many 80 lb. bags of concrete mix are needed to fill an oil drum, first calculate the volume of the drum. A standard oil drum has a capacity of about 55 gallons, which is approximately 0.2 cubic meters or 7.4 cubic feet. Since an 80 lb. bag of concrete mix typically covers about 0.6 cubic feet, you would need roughly 12 to 13 bags to fill the drum completely.
