Real-World Examples
20×40 ft driveway, 4" deep, pea gravel:
20 × 40 × (4/12) = 266.7 cu ft = 9.9 cu yards / ~13.3 tons
20 × 40 × (4/12) = 266.7 cu ft = 9.9 cu yards / ~13.3 tons
10×10 ft path, 2" deep:
10 × 10 × (2/12) = 16.7 cu ft = 0.6 cu yards / ~0.8 tons
10 × 10 × (2/12) = 16.7 cu ft = 0.6 cu yards / ~0.8 tons
