Answer 2

will fan and medal just please help

Answer 3

If it is scaled up by 10, then all the side lengths are multiplied by 10.

Answer 4

Do you know how to find the surface area?

Answer 5

yeahh and its 174

Answer 6

\[
S = 2lw+2lh+2wh
\]

Answer 7

If you scale it up by 10 \[
S' = 2l'w'+2l'h'+2w'h' = 2(10l)(10w)+2(10l)(10h)+2(10w)(10h)\\
= 100(2lw + 2lh+2wh) = 100S
\]

Answer 8

So the surface area is increased by a factor of \(10^2=100\)

Answer 9

ok so I just multiply each by 10??

Answer 10

??

Answer 11

nvm, I got the answer but I need help with one more

Answer 12

What is the volume of the box if it is scaled down by a factor of 1/10?

Answer 13

The volume would be scaled down by \(1/10^3 = 1/1000\).

Answer 14

ok so what do I do??
