Find the scale factor again.
125 / 27 = ?
OpenStudy (anonymous):
4.62962962962963
OpenStudy (anonymous):
the other way around is 0.216
OpenStudy (igreen):
Oh wait..I did the first question wrong.
It should be:
\(\dfrac{1}{27} = \dfrac{24}{V}\)
Cross multiply, what's 27 * 24?

Yes, that's our answer..I believe your last question is also incorrect..and I'm not sure about this other one.
OpenStudy (anonymous):
where did 27 come from
OpenStudy (igreen):
27 comes from 1/27
We were supposed to do :
1/3^3 which is the same thing as 1/27
OpenStudy (igreen):
This is what we were supposed to do for your last question:
4320/VB = (12/8)^3 = (3/2)^3 = 27/8
27 VB = 8(4320)
Now multiply 8 * 4320
