    Could someone refresh me on figuring yards need based on square footage.

    Example if I have an area of 500 sft do I divide by 9 or 27 and how do you account for depth, say I wanted 3 inches instead of 2? Basic I know but I am drawing blank

    An example is like with concrete, if I measure sqft and divide by 80 I get cubic yards of crete needed based on a 4" base. I guess I could double the dividing number to 160 and I would get my yards needed for a 2 inch base. I am trying to simplify the calculations so I don't have to depend on my computer for everything. I think I am getting slower and I get older :dizzy:

    Go to the maintenance forum, click on the "STICKY" at the top that has the "calculating mulch" thread. It's all there.

    Use this formula:

    feet in length X feet in width / 9 / 36 X number of inches desired = total cubic yards needed.

    There you have it.

    (Square Footage) X (Depth) divided by 27 will give you cubic yards

    (.167) = 2 inch depth
    (.25) = 3 inch depth
    (.33) = 4 inch depth
