@Vocaloid

- Vocaloid

- anonymous

- Vocaloid

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

- anonymous

like what type?

- Vocaloid

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

- anonymous

yes okay i got it

- Vocaloid

do you have a ruler?

- anonymous

yes

- anonymous

i got it

- Vocaloid

ok, how long is the box in centimeters?

- anonymous

let me see

- anonymous

wait i just lost my ruler.. :(

- anonymous

what do i do?

- Vocaloid

go find it! you need it!

- anonymous

ok

- anonymous

ill brb! dont go anywhere

- anonymous

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

- Vocaloid

do you have a measuring tape?

- anonymous

no :(

- Vocaloid

well, ok...

- 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?

- anonymous

ok we will use that :)

- Vocaloid

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

- anonymous

wait how do i find the surface area

- Vocaloid

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

- Vocaloid

please do the math

- anonymous

ok no problem :) what step are we on ?

- Vocaloid

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

- anonymous

ok :)

- Vocaloid

now find the surface area of the box

- anonymous

ok :)

- anonymous

i got 272

- Vocaloid

good, you just finished step 3

- anonymous

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

- Vocaloid

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

- anonymous

ok and what was the dimensions of the box?

- Vocaloid

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

- anonymous

no

- anonymous

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

- Vocaloid

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

- anonymous

ok next step .. number 4

- 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?

- anonymous

give me a sec

- anonymous

length: 80
width: 20
height : 120

- anonymous

whats the answer for step 2? @Vocaloid

- anonymous

@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)?

- anonymous

yes

- anonymous

272

- anonymous

@Vocaloid

- anonymous

@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

- anonymous

oh ok :)

- Vocaloid

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

- anonymous

ok sorry. lol :)

- Vocaloid

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

- anonymous

ok

- anonymous

27,200

- Vocaloid

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

- Vocaloid

find the volume of the box

- anonymous

wait so what was the answer for step 4

- 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

- anonymous

ok ... step 5?

- Vocaloid

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

- Vocaloid

find the volume of the box

- anonymous

192

- Vocaloid

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

- anonymous

ok

- Vocaloid

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

- anonymous

wait so now what do i do?

- anonymous

@Vocaloid

- Vocaloid

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

- anonymous

ok

- anonymous

like this:
l / w / h

- anonymous

@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

- anonymous

wait can you write it out and ill solve it

- anonymous

@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

- anonymous

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

- 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?

- anonymous

no

- anonymous

can you help me with that

- Vocaloid

what is 20 divided by 10?

- anonymous

2

- Vocaloid

right! you know how to divide by 10!
so what is the old length divided by 10? old length = 12

- anonymous

so 12 divided by 10?

- Vocaloid

ahh, sorry, the old length is 8, I keep forgetting
the old length divided by 10 is...?

- anonymous

u cant divide it.. it will be 1.25

- Vocaloid

no, what is 8 divided by 10?

- anonymous

oh

- anonymous

0.8

- Vocaloid

yes!
so, let's go back to what we had before:
new length = old length divided by 10
new width = old width divided by 10
new height = old height divided by 10
the old length is 8
the old width is 2
the old height is 12
what is the new length?
what is the new width?
what is the new height?

- anonymous

i dont get it

- Vocaloid

old length is 8
new length is old length divided by 10
what is the new length?

- anonymous

0.8

- Vocaloid

YES
now, old width is 2
new width is old width divided by 10
what is the new width?

- anonymous

0.2

- Vocaloid

great
old height is 12
new height is old height divided by 10
what is the new height?

- anonymous

1.2

- Vocaloid

PERFECT, we're almost done
new volume = (new length)*(new height)*(new width)
what is the new volume?

- anonymous

0.192

- Vocaloid

great, that's the new volume

- Vocaloid

now let's go back to step 2...

- anonymous

ok

- anonymous

what was the answer

- Vocaloid

I never told you the answer, I'm going to help you find the answer

- anonymous

ok

- Vocaloid

I'm going to draw the box, and I want you to imagine that I'm "slicing" the box, like a loaf of bread

- anonymous

ok

- Vocaloid

|dw:1432861172930:dw|

- Vocaloid

try to imagine that I took a knife and cut through the dotted lines, so that the box gets cut into pieces

- anonymous

ok

- Vocaloid

now, if you look at each slice from the side, each slice is shaped like a rectangle

- Vocaloid

|dw:1432861383242:dw|
(pretend you are looking at the box from the side)

- Vocaloid

each cross-section is shaped like a rectangle, so that's the answer to part 2
do you see the black rectangle I drew in the lower right corner? That's called the "cross-section"

- Vocaloid

alright, we've finished all six parts, is there anything you're still confused about?

- anonymous

no

- Vocaloid

ok, great, we're done then, may I please have a medal? Normally I wouldn't ask but since I spent an hour on this problem, it would be nice :)

- anonymous

wait what do i put for question 2

- Vocaloid

what shape did I draw?

- anonymous

square

- anonymous

rectagle

- Vocaloid

yes, rectangle, do you have any more questions?

- anonymous

what do i put for 6.

- Vocaloid

we just went over this, what is the new volume?

- anonymous

0.192, but i need a complete sentence

- Vocaloid

"The volume after the box is scaled down by a factor of 1/10 is ____." and put the new volume in the blank

- Vocaloid

I'm sorry, it's very clear that you just want me to give you the answers, please do not ask for my help again.

- anonymous

no its not that.. i promisee.. i just dont want to get the wrong answer :) i promise im not trying to get the answers from you <3 i appreciate all the effort you put into this :) im sure ill get an A! love u

- Vocaloid

Please look over everything I've written and make sure you can fill out the rest of the homework yourself. I have already told you everything you need.

- Vocaloid

To make sure you really understand it, pick 3 new numbers (anything is fine) and make sure you can solve the homework problems without my help. That way, you'll know if you really learned the material or not.

- Vocaloid

Good luck!

- anonymous

thank! :)
