Answer 1

Answer:

13cm

Step-by-step explanation:

the longest stick can be placed along the body diagonal of box

therefore

$diagonal = \sqrt{ {l}^{2} + {b}^{2} + {h}^{2} } \\ = \sqrt{ {12}^{2} + {4}^{2} + {3}^{2} } \\ = \sqrt{144 + 16 + 9} \\ = \sqrt{169} \\ = 13cm$

hence we can place a 13cm stick
