How it is calculated
- Area = 20 ft × 10 ft = 200 sq ft.
- Top layer: 200 sq ft × 4 in ÷ 12 = 66.67 cu ft ÷ 27 = 2.469 yd³; × 3,200 lb/yd³ ÷ 2,000 = 3.95 tons.
- Top layer loose: 2.469 yd³ × 1.11 = 2.74 yd³; rounded up to 3 yd³.
- Base layer: 200 sq ft × 12 in ÷ 12 = 200 cu ft ÷ 27 = 7.407 yd³; × 3,200 lb/yd³ ÷ 2,000 = 11.85 tons.
- Base layer loose: 7.407 yd³ × 1.11 = 8.22 yd³; rounded up to 8.5 yd³.
