anonymous
  • anonymous
yes
anonymous
  • anonymous

Vocaloid
  • Vocaloid
ok, how long is the box in centimeters?
anonymous
  • anonymous
let me see
anonymous
  • anonymous
wait i just lost my ruler.. :(
anonymous
  • anonymous
what do i do?
Vocaloid
  • Vocaloid
go find it! you need it!
anonymous
  • anonymous
ok
anonymous
  • anonymous

Vocaloid
  • Vocaloid
do you have a measuring tape?
anonymous
  • 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?
anonymous
  • anonymous
ok we will use that :)
Vocaloid
  • Vocaloid
surface area = 2*L*W + 2*W*H + 2*H*L what is the surface area?
anonymous
  • 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
anonymous
  • anonymous
ok no problem :) what step are we on ?
Vocaloid
  • Vocaloid
please read the problem... we are on step 3
anonymous
  • anonymous
ok :)
Vocaloid
  • Vocaloid
now find the surface area of the box
anonymous
  • anonymous
ok :)
anonymous
  • anonymous
i got 272
Vocaloid
  • Vocaloid
good, you just finished step 3
anonymous
  • 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
anonymous
  • anonymous
ok and what was the dimensions of the box?
Vocaloid
  • Vocaloid
Length = ? Width = ? Height = ? do you remember the three numbers?
anonymous
  • anonymous
no
anonymous
  • 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
anonymous
  • 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?
anonymous
  • anonymous
give me a sec
anonymous
  • anonymous
length: 80 width: 20 height : 120
anonymous
  • anonymous
whats the answer for step 2? @Vocaloid
anonymous
  • 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)?
anonymous
  • anonymous
yes
anonymous
  • anonymous
272
anonymous
  • anonymous
@Vocaloid
anonymous
  • 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
anonymous
  • anonymous
oh ok :)
Vocaloid
  • Vocaloid
also, please stop tagging me, I'm right here...
anonymous
  • anonymous
ok sorry. lol :)
Vocaloid
  • Vocaloid
WAIT, hold on, L = 80, not 120, sorry
anonymous
  • anonymous
ok
anonymous
  • 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
anonymous
  • 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
anonymous
  • 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
anonymous
  • anonymous
192
Vocaloid
  • Vocaloid
great, step 5 is done, now on to step 6
anonymous
  • 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
anonymous
  • anonymous
wait so now what do i do?
anonymous
  • anonymous
@Vocaloid
Vocaloid
  • Vocaloid
divide the length, width, and height by 10 and find the new volume
anonymous
  • anonymous
ok
anonymous
  • anonymous
like this: l / w / h
anonymous
  • 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
anonymous
  • anonymous
wait can you write it out and ill solve it
anonymous
  • 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
anonymous
  • 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?
anonymous
  • anonymous
no
anonymous
  • anonymous
can you help me with that
Vocaloid
  • Vocaloid
what is 20 divided by 10?
anonymous
  • anonymous
2
Vocaloid
  • Vocaloid
right! you know how to divide by 10! so what is the old length divided by 10? old length = 12
anonymous
  • anonymous
so 12 divided by 10?
Vocaloid
  • Vocaloid
ahh, sorry, the old length is 8, I keep forgetting the old length divided by 10 is...?
anonymous
  • anonymous
u cant divide it.. it will be 1.25
Vocaloid
  • Vocaloid
no, what is 8 divided by 10?
anonymous
  • anonymous
oh
anonymous
  • anonymous
0.8
Vocaloid
  • 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
  • anonymous
i dont get it
Vocaloid
  • Vocaloid
old length is 8 new length is old length divided by 10 what is the new length?
anonymous
  • anonymous
0.8
Vocaloid
  • Vocaloid
YES now, old width is 2 new width is old width divided by 10 what is the new width?
anonymous
  • anonymous
0.2
Vocaloid
  • Vocaloid
great old height is 12 new height is old height divided by 10 what is the new height?
anonymous
  • anonymous
1.2
Vocaloid
  • Vocaloid
PERFECT, we're almost done new volume = (new length)*(new height)*(new width) what is the new volume?
anonymous
  • anonymous
0.192
Vocaloid
  • Vocaloid
great, that's the new volume
Vocaloid
  • Vocaloid
now let's go back to step 2...
anonymous
  • anonymous
ok
anonymous
  • anonymous
what was the answer
Vocaloid
  • Vocaloid
I never told you the answer, I'm going to help you find the answer
anonymous
  • anonymous
ok
Vocaloid
  • 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
  • anonymous
ok
Vocaloid
  • Vocaloid
|dw:1432861172930:dw|
Vocaloid
  • Vocaloid
try to imagine that I took a knife and cut through the dotted lines, so that the box gets cut into pieces
anonymous
  • anonymous
ok
Vocaloid
  • Vocaloid
now, if you look at each slice from the side, each slice is shaped like a rectangle
Vocaloid
  • Vocaloid
|dw:1432861383242:dw| (pretend you are looking at the box from the side)
Vocaloid
  • 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
  • Vocaloid
alright, we've finished all six parts, is there anything you're still confused about?
anonymous
  • anonymous
no
Vocaloid
  • 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
  • anonymous
wait what do i put for question 2
Vocaloid
  • Vocaloid
what shape did I draw?
anonymous
  • anonymous
square
anonymous
  • anonymous
rectagle
Vocaloid
  • Vocaloid
yes, rectangle, do you have any more questions?
anonymous
  • anonymous
what do i put for 6.
Vocaloid
  • Vocaloid
we just went over this, what is the new volume?
anonymous
  • anonymous
0.192, but i need a complete sentence
Vocaloid
  • 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
  • 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
  • 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
  • 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
  • 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
  • Vocaloid
Good luck!
anonymous
  • anonymous
thank! :)
