A regular octahedron is one of the platonic solids. Each of its faces is an equilateral triangle.
A cube and a dodecahedron.
A cubeoid is not a platonic solid because it does not have equal edges and angles like a platonic solid. Platonic solids have regular polygon faces where each face, edge, and vertex is the same. Cubeoids have rectangular faces and unequal edges and angles.
equilateral triangles and regular pentagons
A platonic solid is a special kind of polyhedron. A polyhedron is a 3-D figure whose faces are polygons.In a platonic solid all faces are identical regular polygons. A polyhedron has faces, edges, and vertices. The numbers of each are related by Euler's formula, V+F=E+2

A Platonic solid is a solid all of whose face are regular and congruent polygons.There are five of these:A Tetrahedron. Four faces, each an equilateral triangle.Ad InfoA Hexahedron (Cube). Six faces, each a square.An Octahedron. Eight faces, each an equilateral triangle.A Dodecahedron. Twelve faces, each a regular pentagon.An Icosahedron. Twenty faces, each an equilateral triangle.

The 7-faced solid is called a "hexagonal pyramid."
tetrahedron
A solid with a regular polygon for each face is known as a perfect solid.
A regular octahedron is one of the platonic solids. Each of its faces is an equilateral triangle.
6 faces , including 5 triangles and one hexagon . :)
