Answer 1

Answer:

13cm

Step-by-step explanation:

l=12cm

b=4cm

h=3cm

the length of the longest stick that can be placed in a cuboid

= diagonal of the cube  =$\sqrt{l^{2} +b^{2}+h^{2} }$

                                       =$\sqrt{12^{2}+4^{2} +3^{2} }$

                                       =$\sqrt{144+16+9}$

                                       =$\sqrt{169}$

                                       =13cm
