Question

answer it correct.. ​

Answer 1

Step-by-step explanation:

measures of tanks= 20m×15m×6m

volume of tank=1800mcube

so,1800 l of water will remain in tank .

water used by villagers per day=150 l

No of days water will last=1800÷150

=12 days

Answer 2

Solution:

Length of the tank = l = 20 m

Breadth of the tank = b = 15 m

Height of the tank = h = 6 m

Total population of a village = 4000

Consumption of the water per head per day = 150 litres

Water consumed by the people in 1 day = (4000×150) litres = 600000 litres …(1)

Formula to find the capacity of tank, C = l×b×h

Using given data, we have

C = (20×15×6) m^3= 1800 m^3

Or C = 1800000 litres

Let water in this tank last for d days.

Water consumed by all people in d days = Capacity of tank (using equation (1))

600000 d =1800000

d = 3

Therefore, the water of this tank will last for 3 days.
