Let us first find the volume of wood with the given dimensions -

⇒ So volume of wood = 84 × 75 × 64


⇒ 403200 cm³


⇒ Now we got the volume of wood but in the question it is asked that - we need to find out the required volume of wood. so by using the given formula we can find out the required volume of wood .

⇒ Volume of wood = inner dimensions - outer dimension

So the thickness of wood is 2 cm. [ Given ]


Let us find the value of inner dimension -


⇒ {84 - 2} × {75 - 2} × {64 - 2}

⇒ 82 × 73 × 62

⇒ 371123 cm³ is the inner dimension

⇒ Therefore volume of required wood -


⇒ Volume of required wood = inner dimension - outer dimension

= 403200 - 371123

= 32077 cm³



VOLUME OF REQUIRED WOOD = 32077 CM ³
