Find the similarity ratio of a prisik with surface area 64ft2 to a similar prisim with surface area 121ft2 awnsers. a.8: 11 b.11: 8 c. 512: 1; 331 d. 1,331: 512

We know that

surface area smaller prism=[scale factor]²*surface area larger prism
scale factor=√[surface area smaller prism/surface area larger prism]
scale factor=√[64/121]> 0.73

therefore

case a) 8/11> 0.73 is ok
case b) 11/8> 1.375 is not 0.73
case c) 512/1331> 0.38 is not 0.73
case d) 1331/512> 2.6 is not 0.73

the answer is
the option A.8:11
