Construction

Calculate limestone volume and weight needed for a project area.

Formula

Volume (cu yd) = L × W × D(ft) ÷ 27; Tons = cu yd × 1.35
  • Limestone density: ~1.35 short tons per cubic yard (varies by crushed/solid).
  • Add 10% to volume for compaction and waste.
  • 1 short ton = 2000 lbs.

20 ft × 10 ft, 4 in deep

Inputs
  • Length: 20 ft
  • Width: 10 ft
  • Depth: 4 in

20 × 10 × (4/12) = 66.67 cu ft ÷ 27 = 2.47 cu yd × 1.35 = 3.33 short tons.
