what's the definition of a cube

Well one of those blocks alone is itself a cube🤷🏽
On a macro/microcosm level. One block itself forms a cube, within what you have here, 4 blocks can make a cube, 27,
The dimensions themselves make a recipe rather than a cube unless you add another layer. And that extra layer can just be one fractal of a block for an even more enormous cube🤷🏽 ad infinitum
So like... What are the parameters?
by this reasoning, the only right correct answer is you need 0 more
i do not disagree
