A) \[125\text{ }c{{m}^{2}}\]
B) \[214\text{ }c{{m}^{2}}\]
C) \[180\text{ }c{{m}^{2}}\]
D) \[205\text{ }c{{m}^{2}}\]
Correct Answer: A
Solution :
[a] Since, the outer edges of a cubical box is 5 cm. \[\therefore \] Surface area of the outer cubical box \[=5\,{{(edge)}^{2}}\] \[=5\,{{(5)}^{2}}=125\,c{{m}^{2}}\]
