How the math works

  1. Area: 12 ft × 10 ft = 120 sq ft
  2. Volume @ 4": 120 × (4 ÷ 12) = 40.00 cu ft
  3. Add 10%: 40.00 × 1.10 = 44.00 cu ft
  4. Cubic yards: 44.00 ÷ 27 = 1.63 yd³
  5. Tons: 1.63 × 1.4 = 2.28 tons
  6. Truck loads: 5.70 tons ÷ 15 tons per tandem = 1

Trade pro tips

  • At 4" deep, 10x12 takes 2.28 tons — a single dump truck delivery covers it.
  • Build in layers: 4" of #3 (2"–3") stone, 4" of #57, then 2" of crusher run / dense grade on top.
  • Lay non-woven geotextile over clay soil first — it stops stone from sinking.
  • Crown the driveway ½" per foot so water sheds to the sides.
  • Spread with a box blade and compact each layer before the next.
