Question

A river 10m deep and 86m wide is flowing at rate 2km/h find the amount of water that run into the river per minute

Answer 1

Height = depth = 10m = h.
Width = breadth = 86m = b.
Length = 2km per hour = 2000m per 60 min = 100/3 m per minute = l.

Volume = lbh = 100/3 * 10 * 86
=28666.6666 m³ = 28666666.6666 litres.
