    A rhombicosidodecahedron is made of 20 triangles, 30 squares, and 12 pentagons. It’s a special type of polyhedron called an Archimedean solid. That means the sides of every triangle, square, and pentagon are equal in length.

    Rhombicosidodecahedron - Wikipedia

    In geometry, the rhombicosidodecahedron is an Archimedean solid, one of thirteen convex isogonal nonprismatic solids constructed of two or more types of regular polygon faces. It has 20 regular triangular faces, 30 square faces, 12 regular pentagonal faces, 60 vertices, and 120 edges. See more
