\[A=2(wl+hl+hw)\]

pooja195 (pooja195):

now just plug in your numbers

OpenStudy (nightmarenight):

ok is w 4?

OpenStudy (nightmarenight):

and the length 3?

OpenStudy (bibby):

they're arbitrary. as long as you stick with what you pick, it comes out to the same thing I think

OpenStudy (bibby):

lemme try this with your numbers and mine

OpenStudy (nightmarenight):

I got 32

OpenStudy (bibby):

A=2(wl+hl+hw) mine: w=2,h=4,l=3 A=2(wl+hl+hw)=\((2*3+4*3+4*2)=6+12+8=26\) yours: w=4,h=2,l=3 A=2(wl+hl+hw)=12+6+6=20 ok, I lied

OpenStudy (nightmarenight):

Oh I multiplied something wrong

OpenStudy (bibby):

wait I forgot to multiply by 2 on both counts

OpenStudy (bibby):

A=2(wl+hl+hw) mine: w=2,h=4,l=3 A=2(wl+hl+hw)=(2∗3+4∗3+4∗2)=6+12+8=26 yours: w=4,h=2,l=3 A=2(wl+hl+hw)=12+6+8=26 ok, I lied

OpenStudy (nightmarenight):

I got 26

OpenStudy (bibby):

so that means we're both right, 2(26)=52

OpenStudy (nightmarenight):

Is it 52m^2?

OpenStudy (bibby):

aye aye because A=2(wl+hl+hw)=\(2((4m*3m)+(2m*3m)+(4m*2m))=2(12m^2+6m^2+8m^2)=2(26m^2)=52m^2\)

OpenStudy (bibby):

52m^2

OpenStudy (nightmarenight):

yeeeeeeeeeeee thank u bib

OpenStudy (bibby):

no, no thank

OpenStudy (bibby):

YOU
