The volume of a rectangular tank 

                                           $$ l imes b imes h $$\$$ $$ = 80 imes 50 imes h $$ \$$ $$ = 4000 h m^3$$

where 'h' is the height of the tank 

Average displace of water by 500 people = $$ 0.4 imes 500 = 20 m^3 rise tank

now,                                                                           

                                                                             $$ 4000h = 20 $$\$$ $$Rightarrow h = frac1200$$\$$ $$Rightarrow h = 0.005m$$\$$

Hence, rise in level of water h = 0.005 m
