Estimate mulch in cubic yards and bags for a bed.
Mulch volume is the bed area multiplied by the depth in feet. Converting to cubic yards matches bulk delivery, while dividing by a bag's volume gives the bag count. Mulch is sold in bulk by the cubic yard or by small bags, so both figures let you order whichever suits the project.
