Practical Example
Let’s say you are pouring a small concrete slab for a backyard patio:
- Length: 12 ft
- Width: 10 ft
- Thickness: 4 in (0.33 ft)
- Bag size: 94 lb
- Cost per bag: $16
- Waste factor: 7%
Results:
- Volume required: 40 cubic feet (1.48 cubic yards)
- Cement bags required: 9 bags (with waste)
- Estimated cost: $144
This calculation ensures you know exactly how much cement to purchase, preventing unnecessary trips to the supplier or wasted money.
