The Mathematical Theoretical Version (the one I made up):
I am the edge of my shape.
Squared is my face and cubed is my volume.
I have proved over a thousand theorems.
Variable to rational,
Variable to imaginary,
These polygons hold many numbers,
Yet these polygons will remained unsolved.
So, as I calculate,
UNLIMITED BOX WORKS!
The Applicable Practical Version (the one a friend made up):
I am the edge of my shape.
Flat are my sides and sharp are my corners.
I have been created over a thousand times.
Unknown to bounce.
Nor known to roll.
Have withstood pressure to be stacked many times.
Yet, the contents will never be known.
So as I open,
UNLIMITED BOX WORKS!
