Question

The length, breadth and height of cuboidal water tank is 7 m, 6 m and 2 m respectively. If 4200 litre of water is pumped out from the tank. Find the fall in water level in the tank.
Please don't answer if you are not confident and no rubbish​

Answer 1

Answer:

0.05 m (5 cm)

Step-by-step explanation:

Measurements provided:

Length = 7 m

Breadth = 6 m

Height = 2 m

Therefore, volume of the cuboidal water tank = length × breadth × height (lbh)

= 7 × 6 × 2 = $84m^{3}$

In order to convert metre cube into litres, we have to multiply by 1000.

Therefore,

$84m^{3}$ x 1000 = 84,000 litres.

Here, the amount of water pumped out of the tank is 4200 litres.

If 4200 litres of water are pumped out of the tank, the fall of the water level in the tank is 4200/84,000 metres.

= 0.05 metres (5 cm)

Therefore, there is a fall of 5 cm or 0.05 m in the water tank.
