satellite73 (satellite73):

what is a "lateral area"??

OpenStudy (pokiedokie):

base and height?

satellite73 (satellite73):

idk i was asking

satellite73 (satellite73):

a quick google search tells me it is \[(2L+2W)H\]

satellite73 (satellite73):

so \[(2\times 14+2\times 18)\times 2.54\]

OpenStudy (pokiedokie):

oh whoops okay so that would be 162.56

satellite73 (satellite73):

want me to check?

satellite73 (satellite73):

yeah, that is what i get

satellite73 (satellite73):

but i just googled it, so don't take my word for it is that a possible answer?

OpenStudy (pokiedokie):

no :/ hold on let me reread the question to see if i missed something

OpenStudy (pokiedokie):

nope, it's not an answer

satellite73 (satellite73):

ok so i googled again, says is is the surface area except the top and the bottom

OpenStudy (pokiedokie):

oh okay hold on I'm gonna try and see what I can do

satellite73 (satellite73):

oh lord!!

satellite73 (satellite73):

it is 8, not 18 doh

OpenStudy (pokiedokie):

Oh its okay lmao i made the same mistake

satellite73 (satellite73):

i should learn to read \[(2\times 14+2\times 8)\times 2.54\]

OpenStudy (pokiedokie):

111.76 which is an answer, yay!

OpenStudy (pokiedokie):

now just for the surface area

satellite73 (satellite73):

take that number, add the areas of the top and bottom

satellite73 (satellite73):

ok \[11.76+2\times 14\times 8\]

OpenStudy (pokiedokie):

235.76 which isn't an answer

satellite73 (satellite73):
