The ration of the lateral areas of the smaller prism to the larger prism is 8 to 18
The first step is t find the scale factor. Recall,
area = square of scale factor
Thus, scale factor = square root of area
Thus,
[tex]\begin{gathered} \text{scale factor = }\sqrt[]{\frac{8}{18}} \\ \text{Dividing the numerator and denominator by 2, we have} \\ \text{scale factor = }\sqrt[]{\frac{4}{9}} \\ scale\text{ factor = 2/3} \end{gathered}[/tex]Volume = cube of scale factor. Thus,
[tex]\begin{gathered} \text{volume = (}\frac{2}{3})^3 \\ \text{Volume = }\frac{8}{27} \\ \end{gathered}[/tex]
