Mulch Volume Calculation
Volume = Area x Depth (in feet)
Convert depth from inches to feet by dividing by 12. Divide cubic feet by 27 for cubic yards, or divide by bag size for the number of bags. For bulk delivery, 1 cubic yard covers about 108 sq ft at 3 inches deep.
Example Calculation
300 sq ft of beds at 3 inches, using 2 cu ft bags.
- 01Volume = 300 x (3/12) = 75 cu ft
- 02Cubic yards = 75 / 27 = 2.8
- 03Bags = 75 / 2 = 38 bags
