This is a puzzle of fractal geometry. If you double the size of a line, you double its mass. If you double the size of a square, you quadruple its mass. If you double the size of a cube, you octuple its mass.(Multiply by 8) As you multiply the size of an object, its mass changes exponentially! It depends on how many dimensions the object has.
Since the characters are 3-dimensional, you raise the size multiplier to the power of 3.(You can only see 2 dimensions of the characters since images are 2-dimensional.)Afterwards, you multiply their normal sizes by that number, which gives you the solutions shown. Remember what you learned in Algebra? Exponentation is done before multiplication.
