In this lesson, we will learn:
 Identify Similar Solids
 Proof of the Relationships Between Scale Factor, Area Ratio and Volume Ratio
 Given the Scale Factors, Find a Surface Area
 Given the Volumes, Find the Scale Factors
 Scale Factors Doubled, Find a Volume
 Solid: A threedimensional object
 Two solids are similar when the ratios of their corresponding measures are constant.
 Scale factor:
 The ratios of the corresponding measures of two objects.
 A numeric multiplier used for scaling.
 If two similar solids have a scale factor of $\frac{a}{b}$, then
 They have a surface area ratio of $(\frac{a}{b})^{2}$.
 They have a volume ratio of $(\frac{a}{b})^{3}$.
