Answer:
\(\frac{91}{9}\) is the ratio.
Step-by-step explanation:
The surface area of prism 1 is given as = 361 square feet
The surface area of prism 2 is given as = 81 square feet
So, the similarity ratio of prism 1 to prism 2 is given by :
\(\frac{\sqrt{361} }{\sqrt{81} }\) = \(\frac{91}{9}\)
Or this can also be written as = 19:9
