How many regular 3d shapes are there?

There are five Platonic solids: Tetrahedron (or triangular pyramid): 4 triangular faces Cube: 6 square faces Octahedron: 8 triangular faces Dodecahedron: 12 pentagonal faces Icosahedron: 20 triangular faces. Although not a Platonic solid, some people consider a sphere to be a regular 3d shape.

No. All the faces of a Platonic solid are identical regular polygons.


Why is a tetrahedron a platonic solid?

Because a tetrahedron is a triangular based pyramid that has 4 identical faces and 4 faces meet at all the vertices.


A pyramid has how many faces and sides?

A rectangular pyramid has five faces. Sides are the same things as faces. A pyramid with a triangular base has 4 faces. This is the more common type of pyramid in mathematics, as it is a platonic solid.

There are 5. They are the tetrahedron (4 triangular faces), the cube (6 square faces), the octahedron (8 triangular faces), the dodecahedron (12 pentagonal faces), and the icosahedron (20 triangular faces).


What is a solid figure with 6 edges?

A tetrahedron is a solid figure with 6 edges. There's no such thing as solid edges. A tetrahedron is a triangular pyramid, with 4 vertices, 6 edges and 4 triangular faces. In a regular tetrahedron (the first Platonic solid) all triangles are equilateral.

What do the platonic solids look like?

The Platonic solids in modern Euclidean geometry are five regular polyhedra. These are three-dimensional objects that are bounded by regular polygonal faces. They are: Tetrahedron (or triangular pyramid): 4 triangular faces; Hexahedron (cube): 6 square faces; Octahedron: 8 triangular faces; Dodecahedron: 12 pentagonal faces; Icosahedron: 20 triangular faces. See link for more.


What are platonic solids and what do they look like?

The five Platonic solids are regular polyhedra. They are convex shapes which are created from regular polygonal faces, such that the number of faces meeting at each face is the same.The five are:tetrahedron - 4 triangular faces;hexahedron (or cube - 6 square faces;octahedron - 8 triangular faces,dodecahedron - 12 pentagonal facesicosahedron - 20 triangular faces.To see their images, search Google for Platonic Solids.
