Answer 1

Given : Length = 10 cm.

Given : Breadth = 9 cm.

Given : Width = 2.5 cm.

We know that Volume of the outer metal= l * b * h

⇒ 10 * 9 * 2.5

⇒ 225 cm^3.

Given that thickness is 0.5 cm.

⇒ Length = 10 - (0.5 + 0.5)

                = 9 cm.

⇒ Breadth = 9 - (0.5 + 0.5)

                  = 8 cm.

⇒  Width = 2.5 - (0.5)

               =  2 cm.

So, volume of the inner metal = l * b * h

⇒ 9 * 8 * 2

⇒ 144 cm^3.

Now,

Volume of the metal = 225 - 144

⇒ 81.

Therefore, Volume of the metal = 81 cm^3.

Hope this helps!
