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

The ratio of the surface areas are 361/81. 

surface area is a 2D measurement.

similarity is a 1D ratio.

square root of 361/81 is 19/9.

5/32 + 5/32 (2 wall thicknesses of the pipe) =10/32

167/32 - 10/32 = 157/32

= 4 29/32
