Equations

For a regular octahedron of edge-length 2R

  • Volume
  • Projected (xy) surface area
  • Surface area


Pyramid

The Octagon shaped can be considered to be formed from two square-based pyramids. Similarly the form factor can be computed from appropriate summation of two pyramid form factors.
