Total Area: square feet (see below for area calculations)

Desired Thickness of Topsoil or Mulch: inches


Total Cubic Yards Needed: (Round up)

Area Calculations: 
Draw your site as accurately as possible - graph paper works well. For odd or complex shapes, divide the area into combinations of rectangles, triangles, and/or circles. Use the following formulas to determine area:

How to determine the area of a CIRCLE:
Multiply pi ( = 3.14) by the square of the radius, If you know the diameter, the radius is 1/2 of the diameter.

How to determine the area of a RECTANGLE or PARALLELOGRAM: 
Multiply the base times the height.

How to determine the area of a TRIANGLE: 
Multiply the base times one-half the height.

How to determine the area of a TRAPEZOID:
Add the lengths of the 2 parallel sides, divide by 2 to get the average length of the parallel sides. Multiply this by the height (distance between the parallel sides)
