PROBLEM TO BE SOLVED: To provide a model for making correlations between rhombus polyhedrons and regular polyhedrons easy to understand since the both are individually explained and their correlations are not touched on. SOLUTION: Transparent plastic rhombus polyhedrons and regular polyhedrons are combined in the order of a regular hexahedron (small)and a regular octahedron, a rhombus dodecahedron, a regular dodecahedron and a regular icosahedron, a rhombus thirty-surface body, and a regular hexahedron (large), and materials of ridge lengths, distances, surface areas, volumes, etc., are attached as a table.
