Question

.-.

Answer 1

the scaling factors of the solids using volumes is

\[1331:729 ... or ... (11)^3:(9)^3\]

so the ratio of the linear measurements is 11:9

so you can use this to help with the surface area

as area ratios are the linear ratios squared

so

\[\frac{605}{11^2} = \frac{x}{9^2} \]

now just solve for x

Answer 2

405?
