Answer 1

Given Population of village = 4000.

Given Water required per head per day = 150 liters.

Therefore the quantity of water required per day = 4000 * 150

                                                                                   = 600000litres

                                                                                   = 600000/1000 m^3

                                                                                   = 600m^3.


Given length = 20m.

Given breadth = 15m.

Given height = 6m.

We know that Volume of the tank = l * b * h

                                                         = 20 * 15 * 6

                                                         = 1800m^3.



Therefore, the required number of days = 1800/600

                                                                    = 3.


Hence, the water will last for 3 days.


Hope this helps!
