Example Calculation
Imagine you’re building a 10 ft x 8 ft slab that’s 4 inches thick, using 80 lb Quikrete Concrete Mix bags.
- Convert 4 inches to feet: 4 ÷ 12 = 0.333 ft
- Multiply: 10 × 8 × 0.333 = 26.64 cubic feet
- One 80 lb Quikrete bag fills about 0.6 cubic feet
- 26.64 ÷ 0.6 = 44.4 bags
✅ You’ll need approximately 45 bags of 80 lb Quikrete Concrete Mix for this project.
