so, water flowing into the sea= area of cross section x rate of flowing water

= 90 x 3000

= 270000 m^3

there water flowing per minute= 270000 / 60 = 4500 m^3

h=2m

b=45m

3km/h=3*5/18m/s=5/6m/s

therefore in one sec 5/6m of water flows in the river

l=5/6m

volume=lbh=2*45*5/6

=15*5=75cu.m=75000litres
