Mulch Requirements
Volume calculation: 0.0 sq ft × 0.167 ft = 0.0 cu ft
Bag calculation: 0.0 cu ft ÷ 2.0 cu ft per bag = 0 bags
Coverage per bag: 12.0 sq ft at 2 inches depth
Mulching Tips
Example Calculation
Garden Bed Example
Area: 10 ft × 6 ft rectangle = 60 sq ft
Depth: 3 inches = 0.25 ft
Mulch type: Wood chips (2 cu ft bags)
Volume needed: 60 × 0.25 = 15 cu ft
Result
Bags needed: 15 ÷ 2 = 8 bags (rounded up)
Total weight: 8 × 20 lbs = 160 lbs
Cost estimate: 8 × $3.50 = $28.00

Mulch Installation Guide
Preparation
Remove weeds, edge beds, and water soil before applying mulch. Install landscape fabric if desired.
