Gravel / Sand Estimate
66.67 ft³ · 3.17 tonnes of Crushed stone (¾″ aggregate)
Step-by-step calculation
Formula
Volume = length × width × depth. Weight = volume × density. 1 cu yd = 0.7646 m³.
- 1Area: 20 × 10 = 200.00 ft².
- 2Depth: 4 inches = 0.333 ft.
- 3Volume: 200.00 × 0.333 = 66.667 ft³.
- 4In cubic yards (US convention): 2.469 cu yd.
- 5Density of Crushed stone (¾″ aggregate): 1680 kg/m³.
- 6Weight: 1.888 m³ × 1680 = 3171 kg = 3.17 tonnes.
