Answer 1

22 inches

Explanation:

The longest stick that will fit in the box will be equal to the length of diagonal of the box.

Length of diagonal is given as:

`d = \sqrt{ {l}^(2) + {w}^(2) + {h}^(2) } \\ = \sqrt{ {20}^(2) + {6}^(2) + {6}^(2) } \\ = √( 400 + 36 + 36) \\ = √(472) \\ = 21.725561 \\ = 22 \: inches`
