# Cubes

A cube is a three-dimensional solid object bounded by **six faces or sides**, with three meeting at each **vertex**. Thus, a cube is a solid with six congruent square faces. The cube can also be called a regular hexahedron.

In a cube - length, breadth and height are same while in a cuboid these are different.

### Parts of a Cube

**Face:** Also called facets or sides. A cube has 6 faces which are all squares, so each face has four equal sides and all four interior angles are right angles.

**Edge:** A line segment formed where two edges meet. A cube has 12 edges. Because all faces are squares and congruent to each other, all 12 edges are of the same length.

**Vertex:** A point formed where three edges meet. A cube has 8 vertices.

### Volume of a Cube

If a is the side length of cube, then its volume = a^{3}
