How do you guys figure the amount of mulch needed for a job? Is there a formula that you can plug numbers into to figure out? and is it the same formula for samll stones/ gravel? Thanks

27 cu ft in a cu yd.

take your width times your length and multiply that by your depth (will be a decimal. say 3 inches would be .25 because 3 inches is .25 of one foot) and that will be your cu ft you need. divide that number by 27 and you get how many cubic yards you need to complete the job.

If you're going bagged it takes 9ea 3 cuft bags per cu yd or 13.5ea 2 cu ft bags.
