A river 3 m deep and 40 m wide is flowing at the rate of 2 km per hour. How much water will fall into the sea ina minute?

Given,

Depth of river = 3m

Width of river = 40 m

Rate of flow of river = 20km/h

Length of river = distance travelled by water in 1 minute at speed 2km/h

=

So, volume of water =
