OpenStudy (anonymous):

lets start with the first step :)

OpenStudy (anonymous):

?? pleaseeeeeee!!!!

OpenStudy (anonymous):

@Vocaloid

Vocaloid (vocaloid):

alright, have you found a box yet?

OpenStudy (anonymous):

how do i find that? can you pick one? @Vocaloid

Vocaloid (vocaloid):

it says to look around your house and find a box go find a box

OpenStudy (anonymous):

like what type?

Vocaloid (vocaloid):

it doesn't matter, do you have a cereal box in the kitchen?

OpenStudy (anonymous):

yes okay i got it

Vocaloid (vocaloid):

do you have a ruler?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

i got it

Vocaloid (vocaloid):

ok, how long is the box in centimeters?

OpenStudy (anonymous):

let me see

OpenStudy (anonymous):

wait i just lost my ruler.. :(

OpenStudy (anonymous):

what do i do?

Vocaloid (vocaloid):

go find it! you need it!

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

ill brb! dont go anywhere

OpenStudy (anonymous):

i cant find it ! :( what can i use? @Vocaloid

Vocaloid (vocaloid):

do you have a measuring tape?

OpenStudy (anonymous):

no :(

Vocaloid (vocaloid):

well, ok...

Vocaloid (vocaloid):

the average cereal box is about 2 inches wide, 12 inches tall, and 8 inches long, Width = 2 inches Height = 12 inches Length = 8 inches, ok?

OpenStudy (anonymous):

ok we will use that :)

Vocaloid (vocaloid):

surface area = 2*L*W + 2*W*H + 2*H*L what is the surface area?

OpenStudy (anonymous):

wait how do i find the surface area

Vocaloid (vocaloid):

L = 8 W = 2 H = 12 Surface Area = 2*L*W + 2*W*H + 2*H*L

Vocaloid (vocaloid):

please do the math

OpenStudy (anonymous):

ok no problem :) what step are we on ?

Vocaloid (vocaloid):

please read the problem... we are on step 3

OpenStudy (anonymous):

ok :)

Vocaloid (vocaloid):

now find the surface area of the box

OpenStudy (anonymous):

ok :)

OpenStudy (anonymous):

i got 272

Vocaloid (vocaloid):

good, you just finished step 3

OpenStudy (anonymous):

ok what was the answer for step 1 and 2 again please:)

Vocaloid (vocaloid):

step 1 is the dimensions of the box I'll get back to step 2 later

OpenStudy (anonymous):

ok and what was the dimensions of the box?

Vocaloid (vocaloid):

Length = ? Width = ? Height = ? do you remember the three numbers?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

oh wait yes i do .. you can continue :)

Vocaloid (vocaloid):

great, "dimensions" just means, what is the length, what is the width, and what is the height? that's all

OpenStudy (anonymous):

ok next step .. number 4

Vocaloid (vocaloid):

ok, so, when we "scale" the box by a factor of 10, it becomes 10 times longer, 10 times wider, and 10 times taller what is the new length, width, and height after we multiply each by 10?

OpenStudy (anonymous):

give me a sec

OpenStudy (anonymous):

length: 80 width: 20 height : 120

OpenStudy (anonymous):

whats the answer for step 2? @Vocaloid

OpenStudy (anonymous):

@Vocaloid

Vocaloid (vocaloid):

I already told you, I'm going to get back to step 2 later, please be patient ok, you found the new length, width, and height. what is the surface area? (using length = 80, width = 20, and height = 120)?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

272

OpenStudy (anonymous):

@Vocaloid

OpenStudy (anonymous):

@Vocaloid

Vocaloid (vocaloid):

no, please use the length, width, and height that you just found. L = length = 120, W = width = 20, H = height = 120 Surface area = 2*W*H + 2*L*W + 2*H*L

OpenStudy (anonymous):

oh ok :)

Vocaloid (vocaloid):

also, please stop tagging me, I'm right here...

OpenStudy (anonymous):

ok sorry. lol :)

Vocaloid (vocaloid):

WAIT, hold on, L = 80, not 120, sorry

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

27,200

Vocaloid (vocaloid):

perfect, now go to step 5 Volume = L*W*H IMPORTANT: use the original dimensions from step 1!

Vocaloid (vocaloid):

find the volume of the box

OpenStudy (anonymous):

wait so what was the answer for step 4

Vocaloid (vocaloid):

step 4: what is the surface area of the box after it has been scaled up by 10?? please try to concentrate on what is being asked

OpenStudy (anonymous):

ok ... step 5?

Vocaloid (vocaloid):

I just told you: volume of the box = L*W*H using the dimensions from step 1

Vocaloid (vocaloid):

find the volume of the box

OpenStudy (anonymous):

192

Vocaloid (vocaloid):

great, step 5 is done, now on to step 6

OpenStudy (anonymous):

ok

Vocaloid (vocaloid):

"scaling down" means that the length, width, and height are divided by 10. Using these new dimensions, find the volume of the box

OpenStudy (anonymous):

wait so now what do i do?

OpenStudy (anonymous):

@Vocaloid

Vocaloid (vocaloid):

divide the length, width, and height by 10 and find the new volume

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

like this: l / w / h

OpenStudy (anonymous):

@Vocaloid

Vocaloid (vocaloid):

No, no, that's not what I meant new length = old length/10 new width = old width/10 new height = old height/10 find the new length, new width, and new height

OpenStudy (anonymous):

wait can you write it out and ill solve it

OpenStudy (anonymous):

@Vocaloid

Vocaloid (vocaloid):

Please stop tagging me, I won't say it again. I already wrote it out for you: the old length is 8 inches the old width is 2 inches the old height is 12 inches the new length = old length/10 new width = old width/10 new height = old height/10

OpenStudy (anonymous):

so i have to divide by the new length or old?

Vocaloid (vocaloid):

please, just follow what I wrote out: new length = old length/10 new width = old width/10 new height = old height/10 find the new length, new width, and new height, using the old length, old width, and old height divide the old length by 10 divide the old width by 10 divide the old height by 10 do you know how to divide by 10?
