Answer 2

Answer:

Read fully,

It's too lengthy for 5points.

hence I would like to give you an understanding with this.

There is a thickness involved here and hence there will be two figures kind, imagine like hollow cylinder with thickness.

hence similarly here we have outer and inner figures,

let V1 be the volume of Outer room and let V2 be the volume of inner room so,

The volume of the wall = V1 - V2.

I hope it's clear.

Hope it helps.
