Concrete volume
AI explanation
Formula
Volume = length × width × thicknessWorked example
8m × 3m driveway, 150mm thick
| Field | Value |
|---|---|
| Driveway length (m) | 8 |
| Driveway width (m) | 3 |
| Thickness (m) | 0.15 |
| Concrete volume | 3.6 |
Assumptions
- Assumes a concrete driveway — for a gravel or asphalt driveway instead, see the Gravel Calculator or Asphalt Calculator, which use material-specific density figures.
Frequently asked questions
How thick should a driveway be?
100-150mm (4-6 inches) is typical for a residential concrete driveway; areas with heavier vehicle loads may need more.
I need the cement/sand/aggregate breakdown too — where's that?
Use the Concrete Calculator or Concrete Slab Calculator with this same volume and your chosen mix ratio.
What if I'm using gravel or asphalt instead of concrete?
See the Gravel Calculator or Asphalt Calculator instead, which use material-specific density figures rather than a mix-ratio breakdown.
