Answer 9

well... I got \(\approx 78\) as well

Answer 10

Similar Solids
Linear Measure Ratio: a:b
Surface Area Ratio: a^2:b^2
Volume Ratio: a^3:b^3

Volumes: " 1,331 m3 and 216 m3"

Volume Ratio: 1331:216 ==> 11^3:6^3
Surface Area Ratio: 11^2:6^2

\(\dfrac{11^{2}\;m^{2}}{6^{2}\;m^{2}} = \dfrac{484\;m^{2}}{Small}\rightarrow Small = 144\;m^{2}\)
