Two similar solids have a scale factor of 6 : 7. What is the ratio of their volumes, expressed in lowest terms?
2 answers:
The ratio of volumes is equal to the ratio of the cubes of the scale factor. Thus,
Volume ratio:
6³ : 7³
216 : 343
Answer:
The ratio of their volumes is equal to
Step-by-step explanation:
we know that
If two solids are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube
Let
z-----> the scale factor
x/y----> the ratio of its volumes
so

we have

substitute


rewrite
-----> the fraction is irreducible
