What to use for this size

A 10×20 area suits a patio base, parking pad, shed base or path. Under pavers or a shed, use 4–6 inches of compacted crusher run; for a decorative area, 2–3 inches of pea gravel over fabric is plenty.

The math

10 × 20 × (4 ÷ 12) = 66.7 cu ft × 1.10 extra = 73.3 cu ft = 2.72 cu yd × 1.4 tons/yd³ = 3.8 tons
