Answer 1

Answer:

Given below with steps:

Step-by-step explanation:

Hello Friend!!

⍟ Depth of river = 3 m

⍟ Breadth or river = 40 m

⍟ Flowing at the rate of = 2km/hour

⍟ 2 km = 2000 m

Q: How much water will fall into the sea in 1 minute?

✤ We have to find volume as the amount of water that will fall into river will be measured by volume.

✤ The river is in the shape of a cuboid.

Formula for volume of cuboid = l × b × h

Therefore volume =  l * b * h

100/3 * 3 * 40

4000 m³

Hope it helped!!

Answer 2

Step-by-step explanation:

first we find,area of river, i.e

area=depth×width

area=3×40

A=120m²

now, flow rate is, 2km/hr

so water fall will be

flow rate×area of river

=(2×1000/60)×120

=4000m³/min
