Formula

surface area = 6 x edge^2

A cube has six equal square faces, so multiply one face area by six.

This measures the full outer area of the cube.

Example

5 units gives Surface Area 150.

Check

Mixing units or scales across edge length before calculating surface area.
Rounding too early when the surface area still feeds another step.
