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
A) 81 : 121  B) 81 : 126  C) 81 : 120  D) 81 : 128  E) 81 : 122
Ratio of the sides = ³√729 : ³√1331 = 9 : 11   Ratio of surface areas = 92 : 112 = 81 : 121   81 : 121nswer: 81 : 121
