Find the cubic yards and tons of crushed stone for a base layer.

Length

Width

Depth

Density (lb/ft³)

Price per ton ($)

Volume 4.444

Weight 6

Total cost ($) 0

Formula: tons = L × W × (depth/12) × density ÷ 2000

Step-by-step with your numbers:

1. Values used:

2. Length = 30

3. Width = 12

4. Depth = 4

5. Density = 100 lb/ft³

6. Price per ton = 0 $

8. Volume = 4.444

Estimate crushed stone for a driveway base, French drain or backfill — in cubic yards and tons.

The math behind it

Volume (ft³) = length × width × depth. Crushed stone ≈ 100 lb/ft³ (~1.35 tons/yd³). Tons = volume × density ÷ 2,000.

30×12 ft at 4 in → 120 ft³ = 4.44 yd³ ≈ 6 tons.

How deep for a driveway base?

4–6 in of compacted crushed stone is typical, sometimes more for heavy vehicles.
