Total Area: square

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

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!
