    The length of the largest rod that can be placed in a room, 16 m long, 12 m broad and \[10\frac{2}{3}m\] high, is

    A) 23 m                

    B) 68 m

    C) 222 m  

    D) 221 m

    Correct Answer: C

    Solution :

    Length of rod \[=\sqrt{{{16}^{2}}+{{12}^{2}}+{{\left( \frac{32}{3} \right)}^{2}}}\] \[=\sqrt{256+144+\frac{1024}{9}}\] \[=\sqrt{\frac{4624}{9}}\] \[=\frac{68}{3}=22\frac{2}{3}m\]
