# Parts of a Cube with Diagrams

The most important parts of cubes are the faces, vertices, and edges. A cube is defined as a three-dimensional figure with 6 faces, 12 edges, and 8 vertices. One of the main characteristics of cubes is that all their parts are equal to each other, that is, the 6 faces are equal, as are the 12 edges. Another important feature is that the faces of the cubes are at right angles to the other faces.

Here, we will learn about the parts of a cube in more detail. We will use diagrams to illustrate each part and describe the faces, vertices, and edges.

## Faces of a cube

Faces are the plane surfaces that bound a cube. In a cube, we have six square faces. All the faces are equal and have the same shape, therefore, the cube is referred to as a regular hexahedron. An important characteristic of cubes is that each of their faces meets the other faces at right angles (90 degrees).

We can calculate the surface area of a cube by adding the areas of the six faces of the cube. Since the faces are square, each area has an area of a², where, a is the length of one of the sides of the cube. Thus, the surface area of a cube is 6a².

## Vertices of a cube

Vertices are referred to as the points where two or more line segments meet. Therefore, we can consider the vertices as the points on the cube, where three edges meet. It is also possible to think of the vertices as the points on the cube, where three faces meet. Cubes have a total of 8 vertices.

## Edges of a cube

An edge is a line segment that is located on the outline of a cube. The edges join two points at the corners of the cube, that is, the vertices. Edges can also be called the line segments where two faces of a cube meet. Cubes have a total of 12 edges. In the diagram, we can see that each edge is shared by two faces of the cube.
