Simple Question !!!
A village, having a population of 4000, requires 150 litres of water per head per day. It has a tank measuring 20 m * 15 m * 6 m. For how many days will the water of the tank last.
Answers
Answer:
Given : 150 litres of water requires per head per day in a village of 4000 population. The dimensions of the tank are 20 m × 15 m × 6 m
We have to find the number of days, the water of this tank will last.
Since the tank is cuboidal in shape, the volume of water in the tank will be equal to the volume of the cuboid.
The volume of cuboid of length l, breadth b, and height h, is l × b × h
First, we will find the requirement of water per day for a total of 4000 population in cubic metres and the volume of the water in the tank.
The number of days for which the water of the tank will last can be obtained by dividing the volume of the water in the tank by the requirement of water per day for the total population.
Requirement of water per head per day is 150 litres.
Requirement of water per day for 4000 population = 4000 × 150L
= 600000L
= 600000/1000 m3 (∵ 1000L = 1 m3)
= 600 m³
Length of the tank, l = 20 m, Breadth of the tank, b = 15 m, and Height of the tank, h = 6 m
The volume of the water in the tank = l × b × h
= 20m × 15m × 6m
= 1800 m3
Number of days for which the water of the tank will last = 1800m3/600m3 = 3 days

I hope it's write answers please mark brainest
Answer:
Volume of the tank = × b × h = (20 × 15 ×6) m3 = 1800 m3 Water required per person per day = 150 litres Water required for 4000 person per day = (4000 × 150) litres = 4000 × 150 × (1/1000) m3 = 600 m3 Number of days water will last = ( )/( ) = ((1800 3)/(600 3)) = 30 Thus
