Volume of a cube

Volume V = s x s x s = s3

Side = s

Example

Calculate the volume of a cube with a side s = 3 cm
Volume V of the cube = s3 = 3 x 3 x 3 = 27 cm3

Definition of a cube

A cube is a solid of six equal square sides.
A cube is a box-shaped solid object that has six identical square faces. It is a solid that has six square faces of equal size that meet each other at right angles.

The volume of a cube can be found by multiplying the edge length three times.
To calculate the volume of a cube, identify the length of the side and multiply the length by itself three times.

A cube has all its faces in a square shape. All the sides have equal dimensions.

To go further

The cube has 6 square faces, 12 edges of the same length and 8 vertices.
All the faces of the cube have the same dimensions.

All faces of the cube are in a square shape.
The angles in a cube are all right angles
The edges opposite to each other are parallel.

Cube or cuboid

What is the difference between a cube and a cuboid ? The difference is that a cube has six square-shaped faces of the same size and a cuboid has rectangular faces.

Differences between a cube and a cuboid:
Faces: a cube and a cuboid have both six faces, all squares for a cube but all rectangles for a cuboid.
Diagonals: a cube and a cuboid have both twelve diagonals on the surface, all equal for a cube, but for a cuboid in sets of four diagonals, each of three different lengths.
A cube and a cuboid have both four internal diagonals, all equal for a cube, but for a cuboid in two pairs of different lengths.

Is every cube a cuboid?

Yes, all cubes are cuboids. A cuboid is a prism with 6 rectangular faces, and a cube is also a prism with 6 rectangular faces. Every cube is a cuboid. Indeed a cube is a special case of the cuboid, where all its dimensions such as length, breadth and height are equal. The cube is a special case of the square cuboid in which all six faces are squares.
