The ratio of the volumes of two cubes is 125 : 1728. What is the ratio of their total surface areas? Choose the correct choice from the following answers
A) 81 : 121 B) 9 : 11 C) 25 : 144 D) 27 : 121 E) None of these
Ratio of the sides = Â³âˆš125 : Â³âˆš1728 = 5 : 12   Ratio of surface areas = 5^2 : 12^2 = 25 : 144   ANSWER:25 : 144
