Dodecahedron (EntityTopic, 12)
From Hi.gher. Space
Equations
- Assumption: Dodecahedron is centered at the origin.
- Variables:
l ⇒ length of edges of the dodecahedron
- The hypervolumes of a dodecahedron are given by:
total edge length = 30l
surface area = 3√(25 + 10√5) · l2
volume = (15 + 7√5)∕4 · l3
- The planar cross-sections (n) of a dodecahedron are:
