OpenStudy (misssmartiez):

So, what is the formular again? A= ( wl x lh x ?) Forgive me, i am sill puzzled.

OpenStudy (misssmartiez):

Explanation. I hate direct answers.

OpenStudy (isaidavila):

Find the área of every rectangle

OpenStudy (misssmartiez):

Those can turn up wrong and I want to gain understanding. My fair tests is coming up, and I want to ace math to be accepted!

OpenStudy (misssmartiez):

You mean cut it up into a net? Yeah, I believe I seek a easier way.

rebeccaxhawaii (rebeccaxhawaii):

A=2(wl+hl+hw) A=2(2x3+4x3+4x2) A=2(6+12+8) A=2(26)

OpenStudy (mrnood):

NO - noyt a net - just see it as 6 separate faces

rebeccaxhawaii (rebeccaxhawaii):

A=52

OpenStudy (misssmartiez):

(Not to you Mr.Nood, to the other owl)

OpenStudy (misssmartiez):

Surface AREA. |dw:1456146929064:dw|

rebeccaxhawaii (rebeccaxhawaii):

OpenStudy (mrnood):

or simply copy @rebeccaxhawaii 's answer

OpenStudy (misssmartiez):

Not the answer choice o.o

OpenStudy (misssmartiez):

OOHHH SORRY WRONG ATTACHMENT XD

OpenStudy (misssmartiez):

FACE PALM

OpenStudy (mrnood):

I'll leave it to @rebeccaxhawaii to GIVE YOU THE ANSWER

rebeccaxhawaii (rebeccaxhawaii):

A=2(wl+hl+hw) A=2(8x10+10x12+8x12)

rebeccaxhawaii (rebeccaxhawaii):

im just simply plugging it in no need to get butt hurt @MrNood

rebeccaxhawaii (rebeccaxhawaii):

so @MissSmartiez what do you get ?

OpenStudy (misssmartiez):

Oh so it is A=2(wl+hl+hw)

OpenStudy (dragonman1):

☻☻☻☻

rebeccaxhawaii (rebeccaxhawaii):

yes it doesnt matter what order

OpenStudy (mrnood):

A paper bag does not have a top face you need to break this down into 5 rectangular sides

rebeccaxhawaii (rebeccaxhawaii):

oh that is true

OpenStudy (misssmartiez):

Umm I got 296?

rebeccaxhawaii (rebeccaxhawaii):

so the bottom is 8x10 then 8x12+8x12+10x12+10x12 is the sides

OpenStudy (mrnood):

Ummm did you ;'got 296' or just guess and wait for someone else to work it out for you? ther are 5 rectangles howabout YOU write down th esides of those 5 shapes?

OpenStudy (misssmartiez):

I don't approve of cursing in my poll. umer, and oh

rebeccaxhawaii (rebeccaxhawaii):

so 80+96+96+120+120=?

OpenStudy (misssmartiez):

OpenStudy (mrnood):

OR just let @rebeccaxhawaii DO IT FOR YOU

OpenStudy (misssmartiez):

OpenStudy (misssmartiez):
