the motion of the monkey is as follows

A monkey moves 6m north (i.e 6m along +y axis),

8m east (i.e  8 m along +x axis) and 10m  vertically upward on a pole (i.e  10m along +z axis)

\text{Displacement of monkey} \ (\vec{s})=8\hat{i}+ 6\hat{j}+10\hat{k}

\text{Magnitude of displacement}\left (|\vec{s} \right |)= \sqrt{8^{2}+6^{2}+10^{2}}=10\sqrt{2}m
