The answer is 24 mm. 3456 divided by 6. Then the square root

The length of a one side of a cube is 24 mm.

What is a cube?

A Cube is a solid three-dimensional figure, which has 6 congruent square faces, 8 vertices and 12 edges. A cube is sometimes also referred to as a regular hexahedron or as a square prism.

For the given situation,

The surface area of a cube = 3456 square mm.

Let the side of a cube be 's'.

The formula of surface area of cube is

[tex]A=6s^{2}[/tex]

On substituting the above value,

⇒ [tex]3456=6s^{2}[/tex]

⇒ [tex]s^{2} =\frac{3456}{6}[/tex]

⇒ [tex]s^{2} =576[/tex]

⇒ [tex]s=\sqrt{576}[/tex]

⇒ [tex]s=24[/tex]

Hence we can conclude that the length of a one side of a cube is         24 mm.
