Question

help w/ geometry

Answer 1

If you can take me through the steps, that'd be awesome.

Answer 2

For first one, the two solids are similar so we can say that :
\[\frac{V_2}{V_1}=a^3\]
Where a is number !
Cam you find
\[a?\]

Answer 3

is this for the first or second one?

Answer 4

It is for the first one !

Answer 5

don't I do like 4* 8 /125 (2/3) or something. I don't remember...

Answer 6

or maybe I switch the 8 and 125.

Answer 7

nvm

Answer 8

You have :
\[a^3=\frac{125}{8}\]
So :
\[a=\sqrt[3]{\frac{125}{8}}=\frac{5}{2}\]

Now you have :
\[\frac{S_2}{S_1}=a^2=\frac{25}{4}\]

Answer 9

ohh okay I see. 25 makes more sense.

Answer 10

so :
\[\frac{S_2}{4}=\frac{25}{4}\]\
so :
\[S_2=25\mathrm{ft}^2\]

Answer 11

Okay. I'm going to need to review that so I remember it. Thank you :)

Answer 12

You are welcome !

Answer 13

Now for the second one, do you know the formula for a right prism?
