## What is a decahedron shape?

## What is a decahedron shape?

In geometry, a decahedron is a polyhedron with ten faces. There are 32300 topologically distinct decahedra, and none are regular, so this name does not identify a specific type of polyhedron except for the number of faces. Some decahedra have regular faces: Octagonal prism (uniform 8-prism)

**How many edges is decahedron?**

30Dodecahedron / Number of edges

A regular dodecahedron or pentagonal dodecahedron is a dodecahedron that is regular, which is composed of 12 regular pentagonal faces, three meeting at each vertex. It is one of the five Platonic solids. It has 12 faces, 20 vertices, 30 edges, and 160 diagonals (60 face diagonals, 100 space diagonals).

### What do the 5 Platonic solids represent?

The 5 platonic solids are considered cosmic solids due to their connection to nature that was discovered by Plato. The cube represents the earth, the octahedron represents the air, the tetrahedron represents the fire, the icosahedron represents the water, and the dodecahedron represents the universe.

**What is a 12 sided 3D shape called?**

In geometry, a dodecahedron (Greek δωδεκάεδρον, from δώδεκα dōdeka “twelve” + ἕδρα hédra “base”, “seat” or “face”) or duodecahedron is any polyhedron with twelve flat faces. The most familiar dodecahedron is the regular dodecahedron with regular pentagons as faces, which is a Platonic solid.

#### What is an example of a decahedron?

A decahedron is a polyhedron having 10 faces. Examples include the augmented pentagonal prism (Johnson solid ), augmented tridiminished icosahedron ( ), nonagonal pyramid, octagonal prism, pentagonal dipyramid ( , square antiprism, and square cupola ( ).

**How many faces does a Hendecahedron have?**

A hendecahedron (or undecahedron) is a polyhedron with 11 faces. There are numerous topologically distinct forms of a hendecahedron, for example the decagonal pyramid, and enneagonal prism.

## Is a cube a hexahedron?

A hexahedron (plural: hexahedra) is any polyhedron with six faces. A cube, for example, is a regular hexahedron with all its faces square, and three squares around each vertex. There are seven topologically distinct convex hexahedra, one of which exists in two mirror image forms.

**How many faces are there in tetrahedron?**

4Tetrahedron / Number of faces

### Is there a sixth Platonic solid?

Meet the Hyper-Diamond! It’s the sixth Platonic Solid and it only works in the fourth dimension.

**Why are Platonic solids so special?**

There are five Platonic Solids. Each one is a polyhedron (a solid with flat faces). They are special because every face is a regular polygon of the same size and shape. Example: each face of the cube is a square.

#### What is a 100-sided 3d shape called?

Zocchihedron is the label of a 100-sided die, a 3d shape. If a 3d shape with 100 faces is called hecatohedron. In case of two dimensional shapes, a shape with 100 sides is called Hectogon. The relationship between the number of faces, edges and vertices of a 3d shape is given by: F + V = E + 2.

**What is a 100-sided shape called?**

A 100-sided polygon is called a hectogon.
