The ditch of Fort Raleigh was divided into 34 separate sectors in order to estimate the volume of the dirt removed and given a unique sector number. These sectors were classified based on their shape as either a trapezoidal prism sector, a corner sector, or a wedge sector. In order to obtain the minimum and maximum estimations, each sector was measured midpoint to midpoint. The Total volume was calculated by the following equation:
Total Volume of Dirt Removed = Volume Of Trapezodial Prism Sectors + Volume Of Corner Sectors + Volume Of Wedge Sectors.
