Question

please answer step by step explanation​

Answer 1

Answer:

Tip: Whenever largest rod is asked it means its diagonal.

Here;

Diagonal=$\sqrt{l^{2}+b^{2}+h^{2} }$

              =$\sqrt{6^{2} +5^{2} +4^{2}$

              =$\sqrt{36+25+16}$

              =$\sqrt{77}$

              = 77^1/2 m

              =77^0.5m.

Hence , The longest rod that can be kept in the room=77^0.5m

                                              Hope it helps!!!!!!
