Dodecahedron Made of Rhombic Triacontahedra

In the last post, I showed that five rhombic triacontahedra can be stuck together to form a pentagonal ring. The next logical step is shown here: using such pentagonal rings to construct an entire dodecahedron made of rhombic triacontahedra.

    1. Thanks again! There are 20 rhombic triacontahedra in this figure. Each normally has 30 faces each, but only 27 are uncovered here, so there are (20)(27) = 540 faces exposed in the whole thing.
