Answer:
Step-by-step 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
