The ratio of the volumes of two cubes is 729 : 1000. What is the ratio of their total surface areas?
Choose the correct choice from the following.
A) 81 : 100
B) 9 : 11
C) 729 : 1331
D) 27 : 121
E) None of these
Ratio of the sides = Â³âˆš729 : Â³âˆš1000 = 9 : 10   Ratio of surface areas = 9^2 : 10^2 = 81 : 100   81 : 100NSWER:81 : 100
