Question

A river 2m deep and 30m wide is flowing at the rate of 2km per hour. How much water will fall into the sea in a minute​

Answer 1

Answer:-

2000 cubic m per minute or 20 lakh litres

Step-by-step explanation:

volume of cuboid = lbh

= 2km * 30m * 2 m

= 2000m * 30m * 2m = 120000 cubic m.

but this is per hour

so per minute = 120000 / 60 = 2000 cubic m

Hope it helps

Mark me as the brainliest

Answer 2

Volume of cuboid = lbh
So
2 km=2000m ( conversion from km to m)
2000m*30m*2m=120000cubic m
So we get the per hour on so we will find per minute one by dividing our result to 60
So here it is
120000
60
That is 2000
