BOX WITHOUT LID :-
Outer length = 112 cm.
Outer breadth = 80 cm.
Outer height = 75 cm.
So, Actual volume of the box = 672000 cm³
EMPTY/HOLLOW PORTION OF THE BOX (INNER BOX STRUCTURE) :-
Inner length = (112-10) cm = 102 cm
Inner breadth = (80-10) cm = 70 cm
Inner height = (75-5) cm = 60 cm
Volume of the inner box structure which is actually empty portion = (102×70×60) cm³ = 499800 cm³
Volume of metal required
= (672000-499800) cm³
= 172,200 cm³
= 172.2 dcm³
