Number one.
i got 1046 for total
how? i keep getting that wrong..
surface area of a rectangular prism = Ph + 2B 56(12) + 2(187) = 1046
i did 56 x 12 x + 2 x 17
oh. one EIGHT seven. howd u get that?
but 187 is B lol
area of the base... 17 x 17?
1 is easy just add up the sides of the figure
you already figured out that B = 187
oh times 11. ok
yes, ma'am
ok. ill correct that.
done
what's the second figure?
triangular prism
yep, and what's the perimeter of the base?
umm, let me add,
42?
btw in the first pic dont include the floor/ base of figure since you dont need to paint that :P
in^2?
ok timo:)
the base of a triangular prism is a triangle, you should get 36 as the perimeter
and i think timo is talking about number 6? we're only on number 2
um,is it not 9+12+9+12?
no, because it's a triangle, not a square or rectangle. so add up 9, 12, and 15
oh. ok.. i get it:)
let me write that
done
b would be..umm..let me calculate..
um, 54?
yep :)
yay! im finally getting it! tnx to the awesome ari! i mean 296!
ok,let me write 54 down.
done
ok, eo,lateral, let me try.
324
no. the lateral area would be the rectangles
oh. but are the formu,as not the same or smthing?
no, they're not. that formula was for a rectangular prism. this is a triangular prism
because it too asks for the lateral area of the triang. prism
can u plz explain for the triang prism?
just find the areas for each of the rectangles and add them together
oh. um, let me try,
438?
no
aah! um, area of a triangle is bh,yes?
you're not trying to find the area of the triangle. you're finding the areas of each of the rectangles
and area of a triangle = bh/2
ohh. so im actually finding the area of rectangles as those a re the laterals'/sides?
yes.
ohh. ok,once more..
um, was it more or less than my last answ er?
...more.
372?
311, i gotta do some chemistry soon. no.
you have to include the 15?
ok,last try. 444.
what's the area of this rectangle?
1 Attachment
yes, 22 x 12, no?
yes, which is...
umm,264
yes. and what's the area of this rectangle?
1 Attachment
umm, 350
594?
why are you guessing? what's 22 x 15?
350
it's 330
and what's the area of this rectangle?
1 Attachment
im using a calculator.
i'm using one too. it's 330
the first i said 264
i put 22*15 into web22.0calc
maybe you should use a different calculator
umm,let me see. then..
http://www.google.com/search?q=scientific+calculator&oq=scie&sugexp=chrome,mod=0&sourceid=chrome&ie=UTF-8
o yea! just used google's
so what's the area of that last rectangle?
um,the first one was 264. the second 330?
what's the area of this rectangle...
1 Attachment
9 x 12?
9 x 22...
umm 198
yes. so what's 198 + 330 + 264?
um 762
792
ok. ill let you alone now. tnx ill search for someone elses hellp if u like
i was gonna finish helping you with this one. you still have to find total surface area
o yea
so 792 is our lateral area, all we have to do is add the areas of those two triangle. what do you get?
triangles*
um... let me se..
is 12 tthe base?
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 = ?
ok. um
900
yes!
does that make sense? what we did?
finally. tnx,ari:) ill stop botheringn u now
um,yes u believe so
i*
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
ok.tnx:)
mayi message u my answers?
is anyone else gonna help you?
i dont think so
:L maybe they will... @Hero @JakeV8
ok. ill try them on my own first
mmk. i'm off the chem. gl :)
off to*
hi jake its only 4 probs
okay 296:) tnx for ur help
no problem :) make sure you tell him you've done one and two on the second link
well, i guess i just did lol. nvm
okay. jake, ive done one and two on the second link:D
what are the P and B things? Help me help you...
and i need not do the bonus
ok. lol p isperimeter of base
b is area of base
And you're up to # 3 on the 2nd link, as sayeth @AriPotta ?
yes
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...
i want to try and talk old fashionedly noe lol
jake pls can u work them out and explain asnu gi along? please?
its 4 probs
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
ok. letnme add.
20
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.
yay! ok, now, b
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
ok,sir
What did you get?
17.2
Jame, Ive to go soon. But, if you leave explanations to thhe three remaining problems,mi will give you a medal.
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.
oops s, jake*
Yes,? please. i am begging you. ill rereadmthe explanation so i get them.
itmis 11:00 pm where i amAnd ive to get up early tmrw
please?
i would very much appreciate itnif u droppedoff thenanswersnhere. i really really need them:/
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
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.
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
um and the height would be 4.3,yes?
no that's the height of the base side. Height of the prism itself is shown as 9
um, ok 180
that's the 3rd part... lateral side area = 120
oops, 180, sorry!!!!!!!!!
i have to go:/ please:/ have mercy:/
3rd part: lateral side area = 180 4th part: total area = 180 + top + bottom = 180 + 17.2 + 17.2 = 180 + 34.4 = 214.4
