Bama Dirt Aggregate Materials Calculator for Rectangles

Dirt Calculator For: Square Or Rectangular Shaped Lawns, Gardens and Cover Areas. This Calculator is for Topsoil, Fill Dirt and Sand Only.

Topsoil Example:
If you have an area that you are planning on putting material on. The first thing you need to know is how wide it is. Lets say your putting topsoil on lawn measure how wide the area in the lawn is that you want to put topsoil in lets use 28 feet. Then measure how long the area in the lawn is. Lets say 30 feet Then how deep do you want the topsoil spread. Lets go with 6 inches. So here is the math

The lawn is 28 feet wide x 30 feet long x 6 inches deep = 420 cubic feet which is also 15.55 cubic yards so lets round it up to 16 yards of topsoil because some holes in the lawn might be a little deeper in some places and shallow in in others.

Remember to always round up your math and add 10% extra for waste on the job.

Calculation Definitions

  • Cubic Inch: A cubic inch is 1 inch wide by 1 inch long by 1 inch deep there are 1728 cubic inches in 1 cubic foot.
  • Cubic Feet: A cubic foot is 12 inches wide by 12 inches long by 12 inches deep there are 27 cubic feet in 1 cubic yard.
  • Cubic Yard: A cubic yard is 3 feet wide by 3 feet long by 3 feet deep.
  • Tons: A ton is a weight measurement and is 2000 pounds in the United States also called a short ton. This one can be confusing when ordering because some products are very heavy and others very light and there are some products sold by the ton and some by the yard For example topsoil is sold by the yard and it weighs about 2400 Lbs. per cubic yard. Where limestone rocks can weigh up to 3000 Lbs. per yard but is sold by the ton.
