To estimate the amount of compost or mulch you will need, follow this calculation:
Example if you are covering an area 8 ft. by 10ft. at the 6 inch dept:
- Multiply the length x width x depth (all in ft.) of the area you are covering. This gives you the cubic feet of material you need.
- Divide the cubic feet by 27 to get cubic yards of materials needed (27 cubic ft. = 1 cubic yd.).
- 8 ft. x 10 ft. x 0.5 ft. = 40 cubic ft
- 40 cubic ft / 27 = 1.48 cubic yards
(approximately 1.5 cubic yards)
