The ratio of the volumes of two cubes is 729 : 1331. What is the ratio of their total surface areas? Choose the correct choice from the following options:
A) 81:122
B) 81:121
C) 81:122
D) 81:197
E) 81:112
Ratio of the sides = ³√729 : ³√1331   = 9 : 11   Ratio of surface areas = 92:112   = 81:121   Answer: 81:121
