Have you ever needed to figure out how much soil or mulch you need?
My Web Guru Friend sent me this Java Script and I have used it and found it pretty handy.

Mulch and Top Soil Calculator
Enter your numbers in the boxes and then press the CALCULATE button

Total Area: square feet (see area calculations below)

Desired Thickness of Topsoil or Mulch: inches

Total Cubic Yards Needed:

Rectangle: Area = length x width

Circle: Area = 3.1416 x the square of the radius

Triangle: Area = 1/2 x length of base x length of height

TIP: Order a little less than you actually may need. You can always bring in more later.
