Question

river 9 m deep and 90 m wide is flowing at the rate of 2 km/hr. Then the volume of water fall into the sea in a minute will be .... *​

Answer 1

Answer:

Here b=90m, h=3m, L= 2km= 2000m

Volume of water fall into the sea in 1 hour = lbh

= 2000×90×3= 540,000m³

Volume of the water flowing in the sea through 1 minute = 540,000/60= 9000m³
