Question
A cubic tank of length 23 cm is to be completely filled with air. What is the volume of air required for the purpose?​

Answer 1

Answer:

length of cubical tank =23 cm

volume of air required = length ^3

=23*23*23

=12167

Answer 2

Step-by-step explanation:

Let each side of cube be of length 'H'.

Given,Volume of water spilled out =

3

1

× H

3

--- (1)

If the surface dip by height 'h'

Then,the volume of spilled liquid = area of triangle×side of cube

=

2

1

×h× H

2

--- (2)

From (1),(2)

3

1

× H

3

=

2

1

×h× H

2

h=

3

2

× H

Angle made by the surface with horizontal be θ,

tanθ =

g

a

(See concept)

From figure, tanθ =

H

h

So, a=g×

H
