The three types of polygons that can be the faces of a Platonic solid are equilateral triangles, squares, and regular pentagons. These polygons must be regular, meaning all sides and angles are equal. The unique arrangement of these faces gives rise to the five distinct Platonic solids: tetrahedron, cube, octahedron, dodecahedron, and icosahedron. Each solid has faces that are identical and meet at each vertex in the same way.
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.
There are no Platonic solids with hexagonal faces because of the geometric constraints related to the angles of regular polygons. A Platonic solid is defined as a three-dimensional shape with identical faces that are regular polygons, and the angles of hexagons do not allow for a convex arrangement that meets the required conditions for a solid. Specifically, the internal angles of a hexagon (120 degrees) are too large to fit together at a vertex in three-dimensional space without overlapping or creating a non-convex shape. Thus, Platonic solids can only be formed from triangles, squares, and pentagons.
Equilateral triangles, squares, regular pentagons.
The solid figure that has two congruent polygons as bases and lateral faces that are rectangles is called a prism. Specifically, if the bases are triangles, it is known as a triangular prism; if the bases are rectangles, it is a rectangular prism. The lateral faces connect the corresponding edges of the two bases, forming a three-dimensional shape.
triangles, squares and pentagons.
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

Answering your questions one at a time.1 - What is a platonic solid?A platonic solid is one with all faces congruent polygons, meaning that they all have the same number of sides, vertices and angle size.2 - How many are there?There are only and exactly five.3 - What are their names?TetrahedronCube (but when talking about Platonic solids, it is commonly referred to as a "hexahedron").OctahedronDodecahedronIcosahedronNote: These individual platonic solids can be identified by their unique Schlafli Symbol. This is demonstrated through the following:{p,q}p = Number of vertices at each faceq = Number of faces at each vertexSo for a dodecahedron, the Shlafli Symbol would be {5,3}, because a pentagon has five {5, or p} vertices, and at any individual vertex three {3, or q} faces meet.Understand? Great!
They are prisms. The bases may be any polygons with three or more sides.
A dodecahedron. A dodecahedron is any polyhedron with twelve faces, but usually a regular dodecahedron is meant. It is a Platonic solid composed of twelve regular pentagonal faces, with three meeting at each vertex. It has twenty (20) vertexes and thirty (30) edges. The dodecahedron would be the Platonic solid with the largest volume if all were made with edges of the same length.
A three dimensional figure with polygonal faces is called a polyhedron. Specific names draw from the Latin prefixes. For example a four sided figure is a tetrahedron.
It's a polyhedron. A polyhedron (plural: polyhedra) is a three - dimensional figure made up of sides called faces, each face being a polygon.

If the question is meant to ask why you cannot make a six sided Platonic solid, the answer is you can - a cube,. If the question is meant to ask why you cannot make a Platonic solid with regular hexagons, the answer is that their interior angles are all 120 degrees. A dihedral angle needs three (or more) faces to meet at a point but three hexagons add up to 360 degrees, which forms a plane - not an angle.
A Platonic shape with four faces is known as a tetrahedron. It consists of four triangular faces, with each face being an equilateral triangle. All edges of a tetrahedron are of equal length, and it is one of the five Platonic solids, which are characterized by their regularity and symmetry. The tetrahedron is the simplest three-dimensional shape in geometry.
