To determine the cost of covering 504 square feet with an 80-pound bag of concrete, follow these steps:
- Calculate the number of bags needed:
Each 80-pound bag covers 25 square feet. To find out how many bags are needed for 504 square feet, divide the total area by the coverage per bag:
504 sq ft ÷ 25 sq ft/bag = 20.16 bags
Since you can’t purchase a fraction of a bag, you’ll need to round up to 21 bags.
- Calculate the total cost:
Each bag costs $4. Multiply the number of bags by the cost per bag:
21 bags × $4/bag = $84
Therefore, it will cost $84 to cover 504 square feet with an 80-pound bag of concrete.
