Strongly speaking, there is no such term and such a notion/(conception) in Geometry as "perimeter of a cube".
There is the term, the notion and the conception of the perimeter of a polygon (triangle, square, parallelogram,
trapezoid, pentagon, hexagon, octagon, decagon and so on . . . )
But not for a cube.
I think that it is more important for you to know the TRUE, rather than to solve incorrectly formulated problems
invented/composed/created by mathematically illiterate people.

You will not find there any mentions about the "perimeter of a cube".
