A box with lid is made of 2cm thick wood. Its external length, breadth and height are 25cm, 18cm and 15cm respectively. How much cubic cm of a liquid can be placed in it? Also, find the volume of the wood used in it.

Explanation

Volume of liquid=l*b*h

`=23*16*13`

`=4784cm^3`

Volume of wood=Volume of extended cube- volume of smaller cuboid

`=(el)(eb)(eh)-(il)(ib)(ih)`

`=25*18*15-23*16*13`

`6750-4784=1966cm^3`.
