Mutual Containing Boxes

thingiverse

If the thickness (t) of boxes and height (h) of the inner box are known, the width (w), length (l) of the inner box and the width (W), height (H) , length (L) of the outer box have the following relationship: H = h + t w = H + 2t W = w + 2t l = W + 2t L = l + 2t A bigger h and a smaller t will make boxes more like a cube so more magical when playing them. Using a smaller h and a bigger t is helpful for understanding why they can contain each other. The original idea is from 黃敏晃, a professor of mathematics retired from National Taiwan University.
