64 : 125
cube both sides
4: 5

cube 4 and 5?

Wait your saying 4:5 is the answer? How'd you get it?

no take the cube of 64 and 125 in order to get 4 and 5 respectively.
yes. 4 and 5 are the answers.

remeber ratios are like simplified equivalents. as long as you do the same to both numbers

Oh okay. Thanks.

I kind a get it. I'm not 100% sure of what you said but sort of.

your saying 64^3 and 125^3 = 4:5?

|dw:1330624579590:dw|

oh the square root! Thank you okay I get it. Sorry I'm a more visual learner. Thank you!

no cube root - that is a 3 not 2

right sorry I made typo

Np - as long as you understand it :)

I don't get what this question is asking me.

|dw:1330624864488:dw|

first, note the issue with height - it was orgiinally 100 and was reduced by 20% to 80

lenght and width were not reduced
now just plug into the equation and you will get your volume

uh huh I'm following

v = 80*5*10

I got the answer!!!!

horray! thank you its 4,000 inches cubed

am i right?

:) yes you are correct

awesome :)

|dw:1330625413364:dw|

Thanks, btw what does ach stand for?

lenght, width, height

Okay thanks.

|dw:1330625924711:dw|

thank u!

uw

Ok so something like this?|dw:1330626458327:dw|

yes

And that's part one?

okay that was easy. but how about part 2?

set up ratios of L W H for both figures
answers will simplfy to 1: 2

So you're saying the ratios of both of these prisms is 1:2? Because is twice as big as the other?

yesyes - all sides are ahve that same ratios since you multiple all sides by 2

ok

so i guess that only leaves part tres

(the two rectangular prisms)
