Answer 9

Hi abbie,
you can use the fact that
Volume of a solid is proportional to cube of the side!
and
Surface Area of the solid is proportional to square of the side!

Answer 10

So,
Since we are given volume of both the solids, lets first find the ratio of sides,

\(\Large \dfrac{V_1}{V_2}= \dfrac{s_1^3}{s_2^3}\)
\(\Large \dfrac{1331}{216}= \dfrac{s_1}{s_2}\)

take cube root on both sides, and you will get the ratio of sides!

Answer 11

that is supposed to be
\(\Large \dfrac{1331}{216}= \dfrac{s_1^3}{s_2^3}\)

Answer 12

know whats the cube root of 1331 and 216 ?

Answer 13

I dont get it...
so what do I have to do?

Answer 14

take the cube root on both sides of
\(\Large \dfrac{1331}{216}= \dfrac{s_1^3}{s_2^3}\)

Answer 15

\(\Large \dfrac{\sqrt[3]{1331}}{\sqrt[3]{216}}= \dfrac{s_1}{s_2}\)

so you will have to find out the cube root of 1331 and 216

Answer 16

11/6

Answer 17

correct! :)

Answer 18

so, the ratio of sides is s1/s2 = 11/6

now since the surface area is proportional to square of sides, we have
\(\Large \dfrac{SA_1}{SA_2} = (\dfrac{s_1}{s_2})^2 \)

\(\Large \dfrac{484}{SA_2} = (\dfrac{11}{6})^2 \)

just find SA2 from this !

Answer 19

what next?

Answer 20

use
11^2 = 121
6^2 = 36

Answer 21

then cross-multiply!

Answer 22

I got 144

Answer 23

and you're absolutely correct! :)
