Find the similarity ratio of a prism with surface area 64 ft2 to a similar prism with surface area 121 ft2

OpenStudy (jack1):

similarity ratio = scale factor... yeah? so lets assume easy prism: cubic prism s1 x s1 x 6 = 64 and s2 x s2 x 6 = 121 so s1 = ( 4 sqrt(2/3)) = approx s2 = (11/sqrt(6) ) = approx so ratio of side lengths = 1 : 1.375 ratio of volumes = 1 : 2.60
