## How to Calculate Concrete Bags Needed
### Formula
**Bags = Total Cubic Feet / Coverage per Bag**
| Bag Size | Yield (cu ft) |
|----------|---------------|
| 80 lb | 0.60 cu ft |
| 60 lb | 0.45 cu ft |
| 40 lb | 0.30 cu ft |
For small projects under 1 cubic yard, bagged concrete is more practical. For larger projects, order ready-mix from a concrete plant.

हल किया गया उदाहरण
A 10 ft by 10 ft slab, 4 inches thick, using 80 lb bags.
- Depth in feet: 4 / 12 = 0.333 ft
- Volume = 10 × 10 × 0.333 = 33.33 cu ft
- Cubic yards = 33.33 / 27 = 1.23 cu yd
- Bags (80 lb) = 33.33 / 0.60 = 55.6 → 56 bags
