Question

a closed box is made of wood 2cm thick and its length breadth and height externally are 80cm 60cm and 50cm find the volume of the wood​

Answer 1

Explanation:

External length=80cm

External breadth=60 cm

External height=50 cm

External volume=l×b×h=80×60×50=240000cm^3

Internal length=80-2-2=76cm

Internal breadth=60-2-2=56 cm

Internal height=50-2-2=46cm

Internal volume=l×b×h=76×56×46=195776cm^3

Volume of wood= External volume-Internal volume=240000-195776=44224cm^3
