A rectangular water tank contains 1440 litres of water. If its length is 120cm and breadth is 80cm, find the height of the water level in the tank.(1 litre=1000cm cube.)

Answer is 150cm

Step-by-step explanation:

Here

l = 120cm

B = 80cm

Rectangular tank contain 1440l of water

As as we know 1l = 1000cm^3

So 1440l = 1440000cm^3

Here,

volume of tank( volume of water) = l *b* h

or, 1440000cm^3= 120cm*80cm* h

or, 1440000cm^3= 9600cm^2* h

h = 150cm

volume of tank( volume of water) = l *b* h

or, 1440000cm^3= 120cm*80cm* h

or, 1440000cm^3= 9600cm^2* h

h = 150cm

Step-by-step explanation:

7.25

step-by-step explanation:
