Question

A river 3meter deep and 40 meter wide is flowing at the rate of 2km per hour . can you find out the volume of water going to the sea per minute?​

Answer 1

We have,Height = 3 m

Breadth = 40 m

length = 2km = 2000 m

time = 1 h = 60 mins

water / hour = 2000/ 60 = 100/3

Volume = l * b * h = 100/3 * 3 * 40 = 4000 m³ = 4000 * 10³ liters

Hope you got the answer.

Hey Mate!!

Given,

Depth = 3 m

Breadth = 40 m

Length = 2 km/hr = 2 × 1000/60 m/min

=> 2000/60 = 100/3 m/min

Volume = length × breadth × height

=> 3 × 40 × 100/3

=> 4000 m^3

Thus, 4000 m^3 of water flows into the sea per minute.

Hope it helps...✌✌
