This question seems to be a popular one in this forum.
A lot of people want to know how to figure out the correct amount of mulch for their landscaping project. So D Felix came up with a good idea to have the formula stuck to the top of this forum.

Here it is:

To determine how much mulch is needed, you take:

Total square feet x depth desired (in feet) / 27 = cubic yards needed

Take square footage time depth desired (in feet, i.e. 3" = .25 feet).
That gives volume in cubic feet.
Divide that number by 27 to get cubic yards. There's 27 cubic feet per yard (3'x3'x3'=27 cubic feet).

Just for you I will make it easier. That way you can do it.

1 Yard of Mulch 3" deep will cover 108 sq feet

1 Yard of Mulch 4" deep will cover 81 sq feet

1 Bag 2 cu feet at 3" will cover 8 sq feet

1 Bag 2 cu feet at 4" will cover 6 sq feet

Not when you are used to the *right* way of doing it.

And especially not when your suppliers handle stuff that way too.

If you use this formula you don't have to convert the depth from inches to feet:

Length (in Feet) X Width (in Feet) X Depth (in Inches) / 324 = Cubic Yards

Example:

Length=10'
Width=20'
Depth=3"
10x20x3/324=1.8518518518518518518518518518519 cubic yards

or

Using the decimal equilivant of 3 inches (.25 feet):

Length=10'
Width=20'
Depth=.25'
10x20x.25/27=1.8518518518518518518518518518519 cubic yards
