Equations

For a regular octahedron of edge-length 2R

  • Volume V_{oct} = \frac{8 \sqrt{2} }{3} R^3
  • Projected (xy) surface area Sp = 4R^2
  • Surface area S_{oct} = 8 \sqrt{3} R^2


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.
