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) 81:131	C) 81:145	D) 81:167	E) 81:113
Ratio of the sides   = ³√729 : ³√1331 = 9 : 11   Ratio of surface areas   = 92 : 112 = 81:121   81:121nswer:81:121
