Question

24.
What is the scale factor of a cube with volume 1,331 ft.3 to a cube with volume 85,184 ft.3? (1 point)

121:1,936
1:64
4:1
1:4

25.
If the scale factor of two similar solids is 3:16, what is the ratio of their corresponding areas and volumes? (1 point)

3:256 and 3:4,096
27:4,096 and 9:256
6:32 and 9:48
9:256 and 27:4,096

26.
The volumes of two similar solids are 1,331 m3 and 216 m3. The surface area of the larger solid is 484 m2. What is the surface area of the smaller solid? (1 point)

864 m2
288 m2
144 m2
68

Answer 1

"Scale Factor" relates to linear measure.

Volume -- 1331:85184 = \(11^{3}:44^{3} = 1^{3}:4^{3}\)
Surface Area -- \(1^{2}:4^{2}\)
Linear Measure -- \(1:4\)

Answer 2

so 1:4 is 24?

Answer 3

You tell me. Now, move on to the next one. The information you need is in the previous discussion.

Answer 4

uh well 1:64 is what i got is tht wrong or is it 1:4

Answer 5

Why would you get that? Didn't I write \(1:4\) clearly enough?

Answer 6

thnxx 25 i got b

Answer 7

How did you get that?

Answer 8

is it wrong? i dont have much time

Answer 9

I'm only interested in you learning. If you don't have the time, feel free to come back when you do.

And, no, B is not correct for 25. You have all the right numbers, but you wandered off when you found all the numbers. You forgot to notice they were in the wrong order.

Answer 10

will u show step by step how to solve
