People say think outside the box. I build frames and to my knowledge a square cannot have 4 perfect sides. Since two sides need to be a little longer to overlap and completed the square. If a box had 4 perfect sides every corner would have to run infinitely and never overlap. What box ? Lol
Same with a circle pi is used to formulated the circle but a physical circle is a complete product. How do you get a finished product from a infinite equation?
