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.
|Trapazoidal Sectors||Corner Sectors||Wedge Sectors||Total|
|Minimum Estimate:||8537.76||994.96||848.9||10381.62 ft^3|
|Maximum Estimate:||10137||1596.5||935.5||12669 ft^3|
|Maximum – Minimum||2287.38|
