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 answers: A) 81:121 B) 81:126 C) 81:221 D) 86:121 E) 81:131
Ratio of the sides = ³√729 : ³√1331   = 9:11   Ratio of surface areas = 92 : 112   = 81:121   81:121nswer: 81:121
