Number one.

- AriPotta

i got 1046 for total

- anonymous

how? i keep getting that wrong..

- AriPotta

surface area of a rectangular prism = Ph + 2B
56(12) + 2(187) = 1046

- anonymous

i did 56 x 12 x + 2 x 17

- anonymous

oh. one EIGHT seven. howd u get that?

- AriPotta

but 187 is B lol

- anonymous

area of the base... 17 x 17?

- anonymous

1 is easy just add up the sides of the figure

- AriPotta

you already figured out that B = 187

- anonymous

oh times 11. ok

- anonymous

yes, ma'am

- anonymous

ok. ill correct that.

- anonymous

done

- AriPotta

what's the second figure?

- anonymous

triangular prism

- AriPotta

yep, and what's the perimeter of the base?

- anonymous

umm, let me add,

- anonymous

42?

- anonymous

btw in the first pic dont include the floor/ base of figure since you dont need to paint that :P

- anonymous

in^2?

- anonymous

ok timo:)

- AriPotta

the base of a triangular prism is a triangle, you should get 36 as the perimeter

- AriPotta

and i think timo is talking about number 6? we're only on number 2

- anonymous

um,is it not 9+12+9+12?

- AriPotta

no, because it's a triangle, not a square or rectangle. so add up 9, 12, and 15

- anonymous

oh. ok.. i get it:)

- anonymous

let me write that

- anonymous

done

- anonymous

b would be..umm..let me calculate..

- anonymous

um, 54?

- AriPotta

yep :)

- anonymous

yay! im finally getting it! tnx to the awesome ari! i mean 296!

- anonymous

ok,let me write 54 down.

- anonymous

done

- anonymous

ok, eo,lateral, let me try.

- anonymous

324

- AriPotta

no. the lateral area would be the rectangles

- anonymous

oh. but are the formu,as not the same or smthing?

- AriPotta

no, they're not. that formula was for a rectangular prism. this is a triangular prism

- anonymous

because it too asks for the lateral area of the triang. prism

- anonymous

can u plz explain for the triang prism?

- AriPotta

just find the areas for each of the rectangles and add them together

- anonymous

oh. um, let me try,

- anonymous

438?

- AriPotta

no

- anonymous

aah! um, area of a triangle is bh,yes?

- AriPotta

you're not trying to find the area of the triangle. you're finding the areas of each of the rectangles

- AriPotta

and area of a triangle = bh/2

- anonymous

ohh. so im actually finding the area of rectangles as those a re the laterals'/sides?

- AriPotta

yes.

- anonymous

ohh. ok,once more..

- anonymous

um, was it more or less than my last answ er?

- AriPotta

...more.

- anonymous

372?

- AriPotta

311, i gotta do some chemistry soon. no.

- anonymous

you have to include the 15?

- anonymous

ok,last try. 444.

- AriPotta

what's the area of this rectangle?

##### 1 Attachment

- anonymous

yes, 22 x 12, no?

- AriPotta

yes, which is...

- anonymous

umm,264

- AriPotta

yes. and what's the area of this rectangle?

##### 1 Attachment

- anonymous

umm, 350

- anonymous

594?

- AriPotta

why are you guessing? what's 22 x 15?

- anonymous

350

- AriPotta

it's 330

- AriPotta

and what's the area of this rectangle?

##### 1 Attachment

- anonymous

im using a calculator.

- AriPotta

i'm using one too. it's 330

- anonymous

the first i said 264

- anonymous

i put 22*15 into web22.0calc

- AriPotta

maybe you should use a different calculator

- anonymous

umm,let me see. then..

- AriPotta

http://www.google.com/search?q=scientific+calculator&oq=scie&sugexp=chrome,mod=0&sourceid=chrome&ie=UTF-8

- anonymous

o yea! just used google's

- AriPotta

so what's the area of that last rectangle?

- anonymous

um,the first one was 264. the second 330?

- AriPotta

what's the area of this rectangle...

##### 1 Attachment

- anonymous

9 x 12?

- AriPotta

9 x 22...

- anonymous

umm 198

- AriPotta

yes. so what's 198 + 330 + 264?

- anonymous

um 762

- AriPotta

792

- anonymous

ok. ill let you alone now. tnx
ill search for someone elses hellp if u like

- AriPotta

i was gonna finish helping you with this one. you still have to find total surface area

- anonymous

o yea

- AriPotta

so 792 is our lateral area, all we have to do is add the areas of those two triangle. what do you get?

- AriPotta

triangles*

- anonymous

um... let me se..

- anonymous

is 12 tthe base?

- AriPotta

the base is the triangle. you've already found the area of the base. it's 54. all you have to do is: 792 + 54 + 54 = ?

- anonymous

ok. um

- anonymous

900

- AriPotta

yes!

- AriPotta

does that make sense? what we did?

- anonymous

finally. tnx,ari:) ill stop botheringn u now

- anonymous

um,yes u believe so

- anonymous

i*

- AriPotta

idk if you already have one or not, or if you can even see it...but i think this will help you:
http://learn.flvs.net/educator/common/StephanieLundy/EOCreferencesheet.pdf

- anonymous

ok.tnx:)

- anonymous

mayi message u my answers?

- AriPotta

is anyone else gonna help you?

- anonymous

i dont think so

- AriPotta

:L maybe they will... @Hero @JakeV8

- anonymous

ok. ill try them on my own first

- AriPotta

mmk. i'm off the chem. gl :)

- AriPotta

off to*

- anonymous

hi jake its only 4 probs

- anonymous

okay 296:)
tnx for ur help

- AriPotta

no problem :) make sure you tell him you've done one and two on the second link

- AriPotta

well, i guess i just did lol. nvm

- anonymous

okay. jake, ive done one and two on the second link:D

- anonymous

what are the P and B things? Help me help you...

- anonymous

and i need not do the bonus

- anonymous

ok. lol
p isperimeter of base

- anonymous

b is area of base

- anonymous

And you're up to # 3 on the 2nd link, as sayeth @AriPotta ?

- anonymous

yes

- anonymous

They show you all three leg-lengths on the picture... one is one the bottom, two are shown on the top. Just add 'em up...

- anonymous

i want to try and talk old fashionedly noe lol

- anonymous

jake pls can u work them out and explain asnu gi along? please?

- anonymous

its 4 probs

- anonymous

look at the diagram... see how it shows one of the bottom sides as 8?
And the top shows the other two sides as 7 and 5
Perimeter = 8 + 7 + 5

- anonymous

ok. letnme add.

- anonymous

20

- anonymous

Adding is good. Reading the diagram and realizing that all you need to do for perimeter is add those 3 sides is even better.
For # 3, P = 20 is correct.

- anonymous

yay! ok, now, b

- anonymous

B is the area of the base.
The formula for area of a triangle is, as you surely know, 1/2 * base * height
Again, the base side has length 8.
And the height is shown as 4.3.
(I'm just reading the diagram... no magic)
So find 1/2 * 8 * 4.3

- anonymous

ok,sir

- anonymous

What did you get?

- anonymous

17.2

- anonymous

Jame, Ive to go soon. But, if you leave explanations to thhe three remaining problems,mi will give you a medal.

- anonymous

Ok, great.
Next is lateral surface area. Check that diagram again... the side surfaces are all rectangles, right? And area of a rectangle is length X width, or length X height (basically one side X the other side).
So, please tell me the the length and height, then multiply to get the area of each of the 3 lateral side surfaces:
Lateral side 1: Length: Height: Length X Height = ?
Lateral side 2: Length: Height: Length X Height = ?
Lateral side 3: Length: Height: Length X Height = ?
This is really easy... it's just reading the length of each edge, and all the heights are the same... then it's easy multiplying... you know how to do this.

- anonymous

oops
s, jake*

- anonymous

Yes,? please. i am begging you. ill rereadmthe explanation so i get them.

- anonymous

itmis 11:00 pm where i amAnd ive to get up early tmrw

- anonymous

please?

- anonymous

i would very much appreciate itnif u droppedoff thenanswersnhere. i really really need them:/

- anonymous

This is like a puzzle... you find the bottom area... and the bottom area is the same as the top area.
Then, you find the side areas... then you add the bottom, top, and all 3 sides together.
You found the bottom area earlier... 17.2. So that's also the top area...
Now you have to find the sum of all the side areas...
All sides are rectangles with area = length X height
So the first is : length1 * height
And the 2nd is : length2 * height
And the 3rd is : length3 * height
And the sum of all three areas is:
length1 * height + length2 * height + length3 * height
But since height is the same, you can think of "distributive property"
and rewrite the lateral side areas as:
height * (length 1 + length2 + length3)
And notice that adding those 3 lengths together is the same as the perimeter, and you already found that to be 20.
So the lateral side area is height * perimeter = height * 20

- anonymous

please please please leave the remaining answers to the third one and fourth on this image and the other two probs on the second image as well youll be rewarded.

- anonymous

So put in the value of the height (height = 9), and solve for lateral side area... that's the 3rd part.
Then, for total surface area, add the lateral side area you just now found to the top area + the bottom area... remember, those were each 17.2
So the total surface area = (9 * height) + 17.2 + 17.2

- anonymous

um and the height would be 4.3,yes?

- anonymous

no that's the height of the base side.
Height of the prism itself is shown as 9

- anonymous

um, ok 180

- anonymous

that's the 3rd part... lateral side area = 120

- anonymous

oops, 180, sorry!!!!!!!!!

- anonymous

i have to go:/
please:/
have mercy:/

- anonymous

3rd part: lateral side area = 180
4th part: total area = 180 + top + bottom = 180 + 17.2 + 17.2
= 180 + 34.4
= 214.4
