Answer 1

Answer:

4000000 litres.

Step-by-step explanation:

given: a river 3 cm deep and 40 cm wide flowing at the rate of 2 km per hour .

Area of the cross section of the river = 4 * 20 = 120 m².

Volume of water flowing through the cross sectionon every minute = Area *rate

120 * 2 km/hr

2*2000

4000m²

since, 1 m³ =1000 ltr

so , 4000 * 1000

4000000 ltr
