Rhombicosidodecahedron
Properties of the rhombicodidodecahedron: Number of faces, edges and dihedral angle measure
The rhombicosidodecahedron is created by either truncating (cutting off) the dodecahedron one half of the way into each side
or by truncating the icosahedron one half of the way into each side
62 total faces:
20 equilateral triangles, 30 squares and 12 regular pentagons
60 vertices:
1 triangle, 2 squares and 1 pentagon
120 edges
Dihedral angles:
148 degrees, 17 minutes for the pent-sqr angle and 159 degrees, 6 minutes for the tri-sqr angle
