The ratio of the volumes of two cubes is 729 : 1331. What is the ratio of their total surface areas?	Options
A) 81 : 121	B) 81 : 127	C) 81 : 191	D) 81 : 161	E) 81 : 182
Explanation:   Ratio of the sides = ³√729 : ³√1331 = 9 : 11   Ratio of surface areas = 92 : 112 = 81 : 121   81 : 121nswer: Option 81 : 121
