In order to determine the volume of the hole, we fill the whole back up with soil with a known unit weight of and determine the amount of that soil it takes to fill the whole.

The assembly includes a plastic jar and metal cone section which screws onto the jar and is placed upon a base plate for stability. When filling the hole with the known sand, the sand will also occupy the volume of the cone and the space between the ground surface and the cone by the base plate. Therefore, these volumes must be calibrated in the laboratory in order to find just the volume of the whole....
