Question

PLease help with this last three part question

Answer 1

7. The volumes of two similar solids are 512 cm3 and 2,197 cm3. If the smaller solid has a surface area of 960 cm2, find the surface area of the larger solid.


Part I: Find the similarity ratio by taking the cube root of each volume. Show your work. (3 points)
















Part II: Use your answer from Part I to find the ratio of the surface areas. Show your work. (3 points)
















Part III: Set up a proportion and solve to find the surface area of the larger solid. (4 points)

Answer 2

Ok

Answer 3

well you have 512cm^3 which the cube root of 512 is 8 and the cube root of 2197 is 13

Answer 4

The ratio is \[(13/8)^2\]

Answer 5

So that is part 1

Answer 6

Yeah

Answer 7

and then part 2

Answer 8

2535/950

Answer 9

2535cm^2/950cm^2

Answer 10

Okay

Answer 11

How did you get that

Answer 12

8²:13² = 960
64:169 = 960
960 = 64(15)
A = 169(15) = 2535 cm²

Answer 13

This is for part 2?

Answer 14

yeah

Answer 15

okay part 3

Answer 16

dont add the 960 = 64(15) A = 169(15) = 2535 cm² to it though because that is part 3

Answer 17

Part three answer should be: 960 * (13/8)² = 2535

Answer 18

so that is part 3
