Question

a village with the population of 4000 required 15 litre of water per day per head it has a tank which is 20 ml long 15 metre broad and 6 hi how for how many days will the water of this tank be used​

Answer 1

Answer:

Given details are, Population of village = 4000 Dimensions of water tank = 20m × 15m × 6m Water required per head per day = 150 litres Total requirement of water per day = 150 × 4000 = 600000 litres Volume of water tank = l × b × h = 20 × 15 × 6 = 1800m3 = 1800000 litres We know that, Number of days water last in the tank = volume of tank / total requirement = 1800000/600000 = 3 days .

Answer 2

Answer:

• The water will last for 30 days.

Step-by-step explanation:

Given that,

• A village having a population of 4,000
• Each person requires 15 litres of water per day.
• A water tank of dimensions 20m long 15m broad and, 6m height.

Capacity of the water tank is given by:

➙ Volume of the cuboid-shaped tank = $l×b×h$

From the given dimensions :

→ V = 20 × 15 × 6

→ V = 1800m³

Here, volume of the cuboid-shaped tank means the capacity of water can be hold by the tank.

Therefore,

Amount of water can be hold in the tank is :

→ (1800 × 1000) litres [$\because$ 1m³ = 1000 litres]

→ 18,00,000 litres

Now,

✦ Water requirement per day by the people :

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎→ 4000*15

‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎→ 60,000 litres.

✦ Number of days the water will last is given by :

$\rm \to \frac{Capacity \: of \: the \: tank}{Water \: requirement \: per \: day }$

$\rm \to \frac{18,00,000}{60,000}$

$\to{\underline{\textsf{\textbf{ 30 days}}}}$
