A) 23 m
B) 68 m
C) \[22\frac{2}{3}\,\,m\]
D) \[22\frac{1}{3}\,\,m\]
Correct Answer: C
Solution :
Length of the largest rod \[=\sqrt{{{L}^{2}}+{{B}^{2}}+{{H}^{2}}}=\sqrt{{{16}^{2}}+{{12}^{2}}+{{\left( \frac{32}{3} \right)}^{2}}}\] \[=\sqrt{256+144+\frac{1029}{9}}\] \[=\sqrt{400+\frac{1029}{9}}\] \[=\sqrt{\frac{3600+1029}{9}}=\sqrt{\frac{4629}{9}}=22\frac{2}{3}\,m\]You need to login to perform this action.
