Step-by-step explanation:
Internal Length (l) = 36-1.5 = 34.5
Internal Breadth (b)= 25-1.5 = 23.5
Internal Height (h) = 16.5 - 1.5 = 15
Volume of box = Iron required = l x b x h
= 34.5 x 23.5 x 15
= 12161.25 cubic cm
Weight of Box = Volume x cubic weight
= 12161.25 x 7.5
= 91209.375 grams
= 91.209375 kg
