Question

A river 4m deep 60m
wide Flowing at a speed of 3 km
per hour. How much water will fall into the sea in half
an hour​

Answer 1

Answer:

Given,

Height = 4m

Breadth = 60 m

Length = 3 km = 1 km = 1000m

= 3 km = 3000m

Time = 30 minutes

Speed of water per hour = 3000 = 50

60

Therefore,

Volume = Length × Breadth × Height

Volume = 50 × 60 × 4

Volume = 12000m cube litres Ans.
