A typical 50 pound bag of sand that you can purchase at a home improvement store is 1/2 cubic foot. There are 27 cubic feet in 1 cubic yard. To figure out how many bags of sand are in a yard, we can use the following equation:
27 cubic feet in a yard ÷ 0.5 cubic foot in a typical 50 lb bag of sand = 54 bags of sand per yard
A yard of sand is equal to 54 bags of sand.
