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 he
