`A = 6* "s" ^2`

Enter a value for all fields

The **Surface Area of a Cube** calculator computes the surface area of the cube based on the equation A = 6•s^{2}, where **s** is the uniform length of the sides. * Cube - All sides of equal length (s) *

**INSTRUCTIONS:** Choose units and enter the following:

- (
**s**) This is the length of one side of the cube.

**Surface Area of a Cube (A):** The area is returned in square meters. However, this can be automatically converted to other area units via the pull-down menu.

Face of one side of a cube is a square of dimensions s by s. The area of a square is:

- A = s x s = s²

There are six equal sides of a cube, so the formula of the surface area of a cube is:

SA = 6•s²

where:

- SA is the surface area of the cube
- s is the length of the sides of the cube
