The Wall of Fort Raleigh
The wall of Fort Raleigh was divided into 30 different 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.
Volume Calculation of the Wall
Total volume was calculated by the following equation:
Total Volume = Volume Trapezoid Sectors + Volume Corner Sectors + Volume Wedge Sectors.
It was assumed that the width of the wall was the same throughout. It was also assumed that the west wall had a gap in it, just as the trench was not completed on the west side of the fort.
| Trapezoid | Wedge | Corner | Total Volume | |
|---|---|---|---|---|
| Minimum Estimate | 6904.3 | 685.984 | 1674.088 | 9264.372 ft^3 |
| Maximum Estimate | 8584.95 | 1171.647 | 2029.28 | 11785.88 ft^3 |
| Maximum-Minimum | 2521.505 |
