Three regular hexagons meeting at a vertex would form a tessellation. So they would form a plane not a solid.
A type of face found on a platonic solid is a regular polygon. Platonic solids are three-dimensional shapes with faces that are congruent regular polygons, and each vertex has the same configuration of faces. For example, a cube has square faces, while a tetrahedron has triangular faces. These regular polygons ensure that the solids have symmetrical properties and are highly structured.

A platonic solid is characterized by having identical faces that are regular polygons. There are five types of platonic solids: the tetrahedron (triangular faces), cube (square faces), octahedron (triangular faces), dodecahedron (pentagonal faces), and icosahedron (triangular faces). Each type has faces that are congruent and meet at the same angle, ensuring uniformity in their geometric structure.
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.

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."

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 . :)
