Practical Example
Let’s say you’re building a 10 ft x 10 ft patio slab that’s 4 inches thick using 80 lb Quickcrete bags.
- Convert 4 inches to feet: 4 ÷ 12 = 0.333 ft
- Calculate volume: 10 × 10 × 0.333 = 33.3 cubic feet
- One 80 lb Quickcrete bag covers about 0.6 cubic feet
- 33.3 ÷ 0.6 = 55.5 bags
✅ You’ll need about 56 bags of 80 lb Quickcrete to complete your patio slab.
