Morphology
The meaning is directly compositional: 'regular' (symmetric, with equal faces) modifies 'dodecahedron' (a twelve-faced solid), so a learner who knows both words can infer a symmetric twelve-faced polyhedron. This follows the normal adjective + noun pattern and is cross-linguistically transparent, so the overall sense is immediately derivable from the parts.
Etymology
Regular dodecahedron comes from Greek parts: dodeca- meaning 'twelve' and -hedron meaning 'face', and regular shows all faces are the same. That's why the name tells you it is a solid with twelve equal 'five-sided' faces.
