Estimates use short tons (2,000 lb). Densities vary by quarry — confirm before ordering.

How the depth-to-volume conversion works

AREA  = LENGTH_ft × WIDTH_ft               → sq ft
VOL   = AREA × (DEPTH_in ÷ 12)             → cu ft
YD³   = VOL ÷ 27                           → cu yd
TONS  = YD³ × DENSITY_(t/yd³)              → short tons (2,000 lb)
COST  = TONS × PRICE_per_TON + DELIVERY

Gravel reference

Material Density (lb/ft³) Density (t/yd³) Drive depth Price / ton Notes
Crushed stone 100 1.35 4–6 in $25–$50 Angular faces interlock and compact — the standard choice for a driveway base and wearing surface.
Pea gravel 96 1.30 3–4 in $30–$60 Smooth rounded stones roll under tires; needs firm edging over a compacted base, or reserve for walkways.
River rock 90 1.22 4–6 in $40–$80 Decorative cobble that stays loose — poor traction on slopes; best for low-speed drives and accents.
