I measured out 16,000 sq ft for a restaurant that needs mulching. I came up with 90 cu yds. Tell me if this is correct for that much sq ft. The price I came up with was 90yd x $65 per yd = $5,850 total how i got cu yd estimate. 16,000 sq ft x .16 then divide that by 27 = 95 but im figuring i should only get about 80-85 since theres alot of shrubs and landscaping in the beds.
