How many 60lb bags of concrete does it take to fill a 3x3x3 hole?

To fill a 3x3x3 hole, you first calculate the volume of the hole, which is 3 feet x 3 feet x 3 feet = 27 cubic feet. A 60-pound bag of concrete typically covers about 0.45 cubic feet. Therefore, to find out how many bags are needed, divide the volume of the hole by the coverage of one bag: 27 cubic feet ÷ 0.45 cubic feet/bag ≈ 60 bags. Thus, it would take approximately 60 bags of 60-pound concrete to fill the hole.
