🧱 Example Calculation
Let’s say you’re building a concrete slab that’s:
- Length: 10 ft
- Width: 4 ft
- Depth: 4 inches (0.33 ft)
Step 1: Calculate Volume
10×4×0.33=13.2 cubic feet10 × 4 × 0.33 = 13.2 \text{ cubic feet}10×4×0.33=13.2 cubic feet
Step 2: Find Quikrete Yield per Bag
An 80 lb Quikrete bag yields about 0.6 cubic feet of concrete.
Step 3: Divide Total Volume by Bag Yield
13.2÷0.6=22 bags13.2 ÷ 0.6 = 22 \text{ bags}13.2÷0.6=22 bags
✅ Result: You’ll need 22 bags of 80 lb Quikrete for this slab.
