The correct option is A True
Given,
The internal length, breadth and height of a closed box are 1m=100cm,80cm and 25cm, respectively.
As its sides are made of 2.5cm, the external length, breadth and
height of the closed box are 100+2(2.5)=105cm,80+2(2.5)=85cm and 25+2(2.5)=30cm, respectively.
Capacity of the box which is cuboidal in shape =105×85×30=267750cm3=0.2m3
