Length x Width = total sq. ft. of area
Total sq. ft. of area (divided) by how deep you want to apply
Fact: 27 cubic feet = 1 Yard
Mulch is sold in 2 cu. ft. bags. 14 bags = 1 cu. Yard
Example: If the Calculator says you require 5 yards of mulch, you will need 70 (2 cubic ft.) bags.
5 (cu. yards) X 14 (bags per yard) = 70 total bags!
