The faces of Platonic solids are regular polygons...
Its a platonic solid :)
A Platonic solid is a convex polyhedron that is regular, in the sense of a regular polygon. Specifically, the faces of a Platonic solid are congruent regular polygons, with the same number of faces meeting at each vertex. They have the unique property that the faces, edges and angles of each solid are all congruent. Some examples are bricks, a dice, tissue boxes and houses.
Because a tetrahedron is a triangular based pyramid that has 4 identical faces and 4 faces meet at all the vertices.
Equilateral triangles, squares, regular pentagons.
A triangle, square or pentagon.
No. All the faces of a Platonic solid are identical regular polygons.

From Wikipedia:A Platonic solid is a convex polyhedron that is regular, in the sense of a regular polygon. Specifically, the faces of a Platonic solid are congruent regular polygons, with the same number of faces meeting at each vertex. Moreover, all its edges are congruent, as are its vertices and angles.

The polygons are the equilateral triangle, the square, and the regular pentagon. The faces of these platonic solids are made from the following polygons: tetrahedron - 4 triangles cube - 6 squares octahedron - 8 triangles dodecahedron - 12 pentagons icosahedron - 20 triangles
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

It is a regular octahedron.
Quite simply, it doesn't fulfill the requirements for a "platonic solid", which include the requirement that all bounding areas must be regular polygons. A square is a regular polygon; a rectangle is not.
