Question

anonymous · Answer

A) 961ft^3
B) 1755ft^3
C) 789ft^3
D) 288ft^3

bahrom7893 · Answer

Okay first of all take the square root of 311ft^2 and 1307ft^2

bahrom7893 · Answer

wait that won't work out.

anonymous · Answer

soo its 311 and 1307ft

anonymous · Answer

ok

anonymous · Answer

hmmmm

bahrom7893 · Answer

The ratio between the volumes squared must be equal to the ratio between the areas raised to the third power

anonymous · Answer

yeah dude your talkin japaneze to me

bahrom7893 · Answer

According to that:
(1307/311)^3 = (1,755/x)^2

bahrom7893 · Answer

74.224 = 3080025/x^2
x^2 * 74.224 = 3080025
x = 3080025/74.224

bahrom7893 · Answer

wait no:
x^2 = 3080025/74.224

but thts not one of my answer choices

bahrom7893 · Answer

yea i see that now.. Im still lookin over my work..

anonymous · Answer

its obviously not b

bahrom7893 · Answer

do you know what the solid is?

bahrom7893 · Answer

Okay let's try the previous method..

bahrom7893 · Answer

the surface areas of two similar solids are 311ft^2 and 1,307ft^2. the volume of the larger solid is 1,755ft^3. what is the volume of the smaller solid?
A) 961ft^3
B) 1755ft^3
C) 789ft^3
D) 288ft^3

anonymous · Answer

no it jus said two similar solids

bahrom7893 · Answer

sqrt(311) = 17.635
sqrt(1307) = 36.152

bahrom7893 · Answer

17.635/36.152 = (x/1755)^(1/3)

bahrom7893 · Answer

0.116 = x/1755

bahrom7893 · Answer

x = 1755*0.116 = 203.58

bahrom7893 · Answer

damn it.. i got the same thing..

C) 789ft^3
D) 288ft^3

anonymous · Answer

Actually I got 203 with 1755 * sqrt(311/1307) all cubed. Then I found http://www.algebra.com/algebra/homework/Surface-area/Surface-area.faq.question.205535.html

bahrom7893 · Answer

YAY!!! Estudier u saved our BOOTIES!!

bahrom7893 · Answer

the answer in the link is right!

anonymous · Answer

But the question is slightly different?

bahrom7893 · Answer

No it's not!

anonymous · Answer

1037 , 1307

anonymous · Answer

So is the question mistyped?

anonymous · Answer

Bizarre. I got 203 ft^3 for that question

anonymous · Answer

Yes, that's what I posted above, I think the question is mistyped and should be 1037, not 1307.

anonymous · Answer

Hmmm

anonymous · Answer

my test  says 1307 idk lool i hope its rite

anonymous · Answer

If it's 1037, then it's D

If it's 1307, then the answer is 203, not in your list.

anonymous · Answer

Don't you know how to compute scale factor jlane?
