To determine how many bags of 80 lb concrete make a cubic yard, you need to know that one cubic yard is equivalent to 27 cubic feet. An 80 lb bag of concrete typically covers about 0.6 cubic feet. Therefore, to fill one cubic yard, you would need approximately 45 bags of 80 lb concrete (27 cubic feet ÷ 0.6 cubic feet per bag ≈ 45).
