1) A village population of 5000. It requires 120L of water per head perday It has a tank measuring 20m by 20m by 3 m. For how many daysthe water of this tank will last?​

Answer»

Answer: 2 days

Given that,

  • A village of population of 5000 PEOPLE and each people REQUIRES 120L of water per day.

Also,

  • The village has a tank which measures 20m by 20m by 3m. Looking at the dimension, It is CLEAR that the tank is in the shape of a cuboid.

Now, lets find the total amount of water REQUIRED by the village per day, which is given by:-

⇒ Water required by 1 person × Population

⇒ 120 × 5000

600,000 L

We know, the VOLUME of a cuboid is given by:-

⇒ Length × Breadth × Height

⇒ 20 × 20 × 3

⇒ 400 × 3

1200

But, we need the volume of the tank in litres in order to find the number of days it is gonna last for, so 1 = 1000 L , hence

Volume of Tank = 1,200,000 L

Now, the number of days the tank is gonna last for is given by:-

⇒ Volume of Tank ÷ Amount of water required per day

⇒ 1,200,000 / 600,000

2

Hence, the tank is gonna last for 2 days.
