Formula

volume = ((15 + 7sqrt(5)) / 4) x edge^3

The regular dodecahedron has a fixed closed-form volume once the edge length is known.

Example

Edge Length 4 gives Volume 490. 44.

Check

Using the right formula with the wrong measurement label or axis.
Switching between degrees and raw ratios without noticing the change.
