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:

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

To determine topsoil requirements for areas of varying grade, use a transit to indicate exact fill requirements...or estimate an average fill depth. Usually soil does not have to be ordered all at once so you can always bring in more...better too little than too much!
