Meet
the Hyper-Diamond
! It’s the sixth Platonic Solid and it only works in the fourth dimension.
How many Platonic solids are in 6 dimensions?
| Polyhedron Vertices Faces | tetrahedron 4 4 | cube 8 6 | octahedron 6 8 | dodecahedron 20 12 |

How many Platonic solids are there?
The
five Platonic solids
(regular polyhedra) are the tetrahedron, cube, octahedron, icosahedron, and dodecahedron.
Is there a 10 sided Platonic solid?
In geometry, a pentagonal trapezohedron or deltohedron is the third in an infinite series of face-transitive polyhedra which are dual polyhedra to the antiprisms. It has ten faces (i.e., it is a decahedron) which are congruent kites.
What is the strongest Platonic solid?
This means that the strengths of 2D and 3D shapes are independent of one another. The project also ended with a conclusion that the
cube, tetrahedron, and octahedron
are the strongest Platonic solids.
What are the 4 Platonic solids?
Platonic solid, any of the five geometric solids whose faces are all identical, regular polygons meeting at the same three-dimensional angles. Also known as the five regular polyhedra, they consist of the
tetrahedron (or pyramid), cube, octahedron, dodecahedron, and icosahedron
.
Are there more than 5 Platonic solids?
In a nutshell:
it is impossible to have more than 5 platonic solids
, because any other possibility violates simple rules about the number of edges, corners and faces we can have together.
What are the duals of the 5 Platonic solids?
As you can see in the main image above, the dual polyhedra of the Platonic solids are all Platonic solids themselves. So, the
cube and the octahedron
are duals of each other; the dodecahedron and the icosahedron are duals of each other; and the tetrahedron is the dual of itself.
How many Platonic solids are in 4 dimensions?
A70, 162-167; DOI: 10.1107/S2053273313034220]. Platonic solids have counterparts in four dimensions, and the Swiss mathematician Ludwig Schlaefli and Alicia Boole Stott showed that there are
six
of them, five of which have very strange symmetries.
What is the order of the Platonic solids?
The ordered number of faces for the Platonic solids are
4, 6, 8, 12, 20
(OEIS A053016; in the order tetrahedron, cube, octahedron, dodecahedron, icosahedron), which is also the ordered number of vertices (in the order tetrahedron, octahedron, cube, icosahedron, dodecahedron).
How do you make a Platonic solid?
- Tetrahedron – Complete the shape by gluing the last circle into the bottom of the three-sided pyramid shape.
- Cube – Glue the two pieces together.
- Octahedron – Glue the two four-sided pyramid shapes together at their bases.
- Dodecahedron – Glue the top and bottom together.
What is a ten sided solid shape called?
In geometry,
a decagon
(from the Greek δέκα déka and γωνία gonía, “ten angles”) is a ten-sided polygon or 10-gon. The total sum of the interior angles of a simple decagon is 1440°. A self-intersecting regular decagon is known as a decagram.
Is a sphere a Platonic solid?
Well, a Platonic solid looks
a lot like a sphere in ordinary
3-dimensional space, with its surface chopped up into polygons. So, a 4d regular polytope looks a lot like a sphere in 4-dimensional space with its surface chopped up into polyhedra!
How many platonic solids consists of triangles?
The five Platonic solids. Named for Plato, who theorized that the classical elements were made of these regular polyhedrons,
three
of the Platonic solids are composed of equilateral triangles: the tetrahedron, octahedron, and icosahedron.
Are all prisms Platonic solids?
A prism is a solid structure with flat faces and identical faces at both ends. As a result,
all prisms are NOT platonic solids
. There have only been 5 platonic solids: the tetrahedron, the octahedron, the icosahedron, the cube, and the dodecahedron.
How do you identify a Platonic solid?
Platonic solids have
polygonal faces
that are similar in form, height, angles, and edges. All the faces are regular and congruent. Platonic shapes are convex polyhedrons. The same number of faces meet at each vertex.
