There are 45 80-pound bags and about 60 60-pound bags of concrete in a cubic yard. Each 80-pound bag of concrete covers about 0.6 cubic feet. There are 27 cubic feet in a cubic yard: 27/.6 = 45.
Know MoreThough the number of 80 pound bags is exact at 45, overestimating the number of bags needed is a common construction practice to account for the minor variations found in building materials. In addition, most building applications do not use perfectly cubed yardage of concrete, as most slabs are poured just four to six inches thick, and footers for deck support tend to be cylindrical.

Full Answer >There are 27 cubic feet in a cubic yard. The formula for a cubic foot is length x width x depth. The cubic foot is a 3-dimensional measurement of a linear formula of volume.
Full Answer >A ton is a measurement of weight, and a cubic yard is a measurement of volume. The number of tons that a given cubic yard of material weighs depends on the material.
Full Answer >There are 14 wheelbarrow loads in a cubic yard for a 2-cubic-foot wheelbarrow, and nine wheelbarrow loads in a cubic yard for a 3-cubic-foot variety. The smaller wheelbarrow has a shallow basin, whereas the larger version is more common. Both wheelbarrows must have a crest to reach the maximum capacity.
