You don’t have to assume any shape for this, as long as the shape remains the same, and that it is not fractal. You could have a spherical fridge and it would still be true.

Why assume that the old fridge will be geometrically proportional to the new fridge? I think that's particularly unlikely to be true in the case of a person replacing their existing refrigerator.
