Answer 3

I think that the area is 282, not 272, please check my value.
Furthermore, every dimension is scaled up by the same factor, namely 10, then your area is scaled up by a factor 10*10 namely 100. so your area is?

Answer 4

oops I think your area is 292, not 272, please check that value

Answer 5

Oh ok

Answer 6

So then its 100 x 292?

Answer 7

that's right!

Answer 8

So then 29,200

Answer 9

Thats the answer?

Answer 10

And this: What is the volume of the box if it is scaled down by a factor of 1/10? I know the volume is 240 in 2

Answer 11

If the volume is scaled by a factor 1/10, then your new volume is:
240/10=...?

Answer 12

24?

Answer 13

that's right!
