Question

A rectangular tank is 10x5x6 full of water hiw much water should be extracted from the tank so that the water level decreases by 1 meter

Answer 1

Volume of tank =300m^3
Height of tank = 6m
Decrease 1 m height
Then volume of tank =(10*5*5)m^3= 250m^3
Therefore water extracted = (300-250)m^3=50m^3
