@AriPotta

OpenStudy (aripotta):

quadrupled. do you remember what i said on the perimeter question by accident? that applies to this :)

OpenStudy (anonymous):

oooh lol

OpenStudy (anonymous):

duh. it says 'area' lol

OpenStudy (aripotta):

yep, and since it's doubled, it would 2^2, or 4 times the original area

OpenStudy (anonymous):

i get it thanks for the thousandth time lol

OpenStudy (aripotta):

would be*

OpenStudy (aripotta):

OpenStudy (aripotta):

36/9 =

OpenStudy (aripotta):

4

OpenStudy (anonymous):

yesh

OpenStudy (anonymous):

so anytime its area its quadrupuled?

OpenStudy (aripotta):

no. anytime the dimensions are doubled, the area is quadrupled

OpenStudy (aripotta):

2^2

OpenStudy (anonymous):

ooh. mk

OpenStudy (aripotta):

if the dimensions were tripled, the area would be 9 times the original area. 3^2

OpenStudy (anonymous):

mk. tnx:)

OpenStudy (aripotta):

and for volume, you would cube it

OpenStudy (anonymous):

^2 every time?

OpenStudy (aripotta):

if the dimensions were doubled, the volume would be 2^3 or 8 times the original

OpenStudy (anonymous):

mhmm. mk.thanks:)
