Answer:
Stress = Force/Area.
Let us assume the man grows only in length and his cross-section area remains same.
Since it is given that density remains same, mass increases by 9 times
Since force is due to his weight(gravitational force on mass) force increases by 9 times.
Hence stress increases by 9 times
