Answer:

Question 4: number of ice-cream bricks = 150

Question 5: 3 days

Explanation:

Question 4:

First we will find volume of brick:

Volume of brick = 20 * 10 * 7 cm^3

Volume of brick = 1400 cm^3

Now find volume of deep freezer:

Volume of deep freezer = 100 * 50 * 42 cm^3

Volume of deep freezer = 210,000 cm^3

Now for finding number of bricks that can be placed in deep freezer:

number of ice-cream bricks = 210,000/1,400

number of ice-cream bricks = 150

______________________________________

Question 5

Given that:

Population = 4000

Per person requirement per day = 150 liters

Total requirement per day = 4,000* 150 = 600,000 liters

Tank has:

length = l =20m

width = w =15.

height = h =6m

So the volume will be:

Volume = l*w*h

By putting values:

Volume = 1,800 m^3

As 1 cubic meter = 1,000 liters So,

Volume = 1,800,000 liters

As the per day requirement is 600,000 liters

So

1,800,000 liters will be last = 1,800,000/600,000 = 3 days

i hope it will help you!
