The ratio of the volumes of two cubes is 125 : 512. What is the ratio of their total surface areas?	Select the correct option:
A) 81 : 121
B) 25 : 64
C) 729 : 1331
D) 27 : 121
E) None of these
Ratio of the sides = Â³âˆš125 : Â³âˆš512 = 5 : 8   Ratio of surface areas = 5^2 : 8^2 = 25 : 64   ANSWER: 25 : 64
