Answer :
Answer:
The scale factor is equal to [tex]0.4[/tex] or [tex]\frac{2}{5}[/tex]
Step-by-step explanation:
we know that
If two figures are similar. then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z------> the scale factor
x------> the volume of the dilated prism
y------> the volume of the original prism
so
[tex]z^{3}=\frac{x}{y}[/tex]
we have
[tex]x=200\ ft^{3}[/tex]
[tex]y=3,125\ ft^{3}[/tex]
substitute
[tex]z^{3}=\frac{200}{3,125}[/tex]
[tex]z=\sqrt[3]{\frac{200}{3,125}}[/tex]
[tex]z=0.4[/tex] or [tex]z=\frac{2}{5}[/tex]
