How it's worked out
- Volume: 12 × 60 × 4 in ÷ 12 = 240 cu ft
- Cubic yards: 240 ÷ 27 = 8.89 yd³
- Tons: 8.89 × 1.4 tons per yard = 12.4 tons

| Depth | Cubic yards | Tons (approx.) | With 10% extra |
|---|---|---|---|
| 2 in | 4.44 | 6.2 | 6.8 |

| 6 in | 13.33 | 18.7 | 20.5 |
A new driveway is usually built in layers: 4 to 6 inches of large crushed stone for the base, then 2 to 3 inches of smaller top stone. Refreshing an existing driveway takes about 2 inches. The 1.4 tons per yard figure is typical for gravel; ask your supplier for theirs.
