How It Works
Volume = L × W × H (in ft) ÷ 27 = cubic yards
L, W, H in feet · 1 yard = 27 ft³
10ft × 10ft × 4in (0.333ft)
- 1Volume = 10 × 10 × 0.333 = 33.3 ft³
- 2÷ 27 = 1.23 yd³
- 3Add 10% waste → 1.36 yd³
Result: ≈ 1.36 cubic yards (14 bags)
Pro Tip
Always order 5–10% extra — short pours are expensive to fix.
