64 : 125 cube both sides 4: 5
cube 4 and 5?
Wait your saying 4:5 is the answer? How'd you get it?

Other answers:

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?

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 have another question: A rectangular prism is truncated removing 20% of its height. The original height of the prism was 100 inches and it has a length of 5 inches and a width of 10 inches. What is the volume of the truncated prism?
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?
Alright I have another question:A triangular prism has a volume of 10 cm3. If each dimension of the prism is multiplied by four, what is the new volume of the prism?
:) yes you are correct
awesome :)
Can you help me solve this: A triangular prism has a volume of 10 cm3. If each dimension of the prism is multiplied by four, what is the new volume of the prism?
|dw:1330625413364:dw|
Thanks, btw what does ach stand for?
lenght, width, height
Okay thanks.
Gotta another one for you: Each dimension of a rectangular prism is increased by 10%. What percent of the original volume is the volume of the new prism?
|dw:1330625924711:dw|
thank u!
uw
I have one more and I just need and example of what how to do this so I can create my own authentic answer. Okay here it is:Part 1: Create and provide the dimensions for two similar figures of your choosing. Part 2: What is the similarity ratio of these figures along with the ratio of their surface area and volume? Part 3: Show your work, either using the actual volumes or using the formula, that the volume ratio is true.
1. easier is rectangular prism make the dimenstions of one and then multiply by 2 to get the dimeensions of the 2nd one
Ok so something like this?|dw:1330626458327:dw|
yes
And that's part one?
okay that was easy. but how about part 2?
Part 2: What is the similarity ratio of these figures along with the ratio of their surface area and volume?
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
Here it is in case you don't remember: Part 3: Show your work, either using the actual volumes or using the formula, that the volume ratio is true.
Wait one second please. Before we go on to three I think there's one thing we didn't finish answering in two. That was: What was the ratio of their surface area and volume?
(the two rectangular prisms)
I think you said that their similarity ratio was 1 : 2. But now I have to find the ratio of their surface area and volume.
I'm doing the same thing now and thank you but evergirl it's kinda cheating when you ask for every single question... lol but I guess google isn't that fair either ;P
