What if we rotated the paper by 90 degrees around its z axis, rather than its x or y axis? (terminology which would also be dependendent on context and a standardised frame of reference) Could we then say that the paper is about 0.07mm long?If I had a piece of A4 paper, held in portrait, then yes, the length would be the longest side (11.7 inches) but if the paper was turned to landscape, the width would be 11.7 inches. The ruler part just goes to prove that people see things differently.
