    How many sqft of coverage should I expect out of a cubic yard of 3-5" river rock?

    I know its a bit of a weird question since I stated in in 'yards' not 'tons'.

    Reason I ask is that I have an area of a potential job in which the customer wants to replace want amounts to 2 yds of mulch @ 2" depth with 3-5" delaware river rock. I'm just trying to see how to convert a 'yard' of 3-5 RR into a 'yard' of mulch. I mean theoritically speaking you can't have a 2" thick layer of this rock since its smallest size is 3".

    Working the calculation backwords I have 325 ft2 I need to cover. Assumming the lower end of the two numbers provided (75) that means I need ~4yds.

    Now, next question. Is 1.8 tons per cubic yard an okay conversion for obtaining the price...so 7.2 tons?

    Or you could do the math yourself. Lenth x width x depth
    THere is 27 cubic feet in a cubic yard.
