How do I figure a mulch job? A ladys entire front house around 40' long by 5' wide. Equal 200 sq. feet. How do I convert into yard. I know the average going rate installed is 60 a yd. Give or take depending on type of mulch. They dump the mulch in my trailer by the yard so I figure it would be easier for bid if I knew cubic yards a customer had. I'm green as you can tell but the help would be appreciated!
