**Introduction:**

The dimension of an object is a topological measure of the size of its covering properties. (Source: Math world). Generally speaking, it is the number of coordinates required to denote a point on the object. For example, a square is two-dimensional, while a cylinder is three-dimensional. The dimension of an object is often called as "dimensionality." Let us see solve three dimensions in this article.

There are several types of dimensions. They are;

- Zero dimension (e.g. Point)
- One dimension(e.g. Line)
- Two dimension (e.g. Square, Rectangle, circle etc...)
- Three dimensions (e.g. cube, Cylinder, Polygon etc...)
- Hyper dimension (e.g. hypercube etc...)

These are the types of dimensions. Let us see to solve three dimensions here.

In order to solve, the three dimensions are generally known as length, width, and depth or height. Any three mutually perpendicular directions can act as the three dimensions.

The examples to solve three dimensions are:

- Tetrahedron
- Cube
- Octahedron
- Dodecahedron
- Icosahedrons
- Cylinder
- Cone

**Tetrahedron:**

Tetrahedron falls under the polyhedron which has the four equilateral triangular faces, four vertices and six edges.

**Image Description:** The above figure is the tetrahedron because it has 4 faces, 4 vertex and 6 edges.

**Cube:**

Cube is also a polyhedron which has 6 faces,12 edges and 8 vertices. The following figure gives the representation of cube.

**Image Description:** The above figure represents the cube - it has 6 faces, 8 vertex and 12 edges.

**Octahedron:**

Octahedron is the polyhedron which has eight faces, six vertices and 12 edges. The following figure represents the octahedron.

**Image Description:** The above figure is the octahedron - it has 8 faces, 6 vertex and 12 edges.

**Dodecahedron:**

** ** Dodecahedron is the three dimensional object which has 12 faces, 30 edges and
20 vertices. The following figure shows the dodecahedron representation.

**Image Description:** The above figure is the dodecahedron - it has 12 faces, 20 vertex and 30 edges.

**Icosahedrons:**

Icosahedrons are the three dimensional object also it falls under the category of platonic solids. It has 20 faces, 30 corners and 12 vertices. The following figure shows the representation of the icosahedrons.

**Image Description:** The above figure is the icosahedron - it has 20 faces, 12 vertex and 30 edges.

**Cone:**

** ** A **cone** is a three dimensional geometric object that diminish
easily from a flat, generally circular base to a point known as the apex or vertex.
