Number one.
AriPotta
  • AriPotta
i got 1046 for total
anonymous
  • anonymous
how? i keep getting that wrong..
AriPotta
  • AriPotta
surface area of a rectangular prism = Ph + 2B 56(12) + 2(187) = 1046
anonymous
  • anonymous
i did 56 x 12 x + 2 x 17
anonymous
  • anonymous
oh. one EIGHT seven. howd u get that?
AriPotta
  • AriPotta
but 187 is B lol
anonymous
  • anonymous
area of the base... 17 x 17?
anonymous
  • anonymous
1 is easy just add up the sides of the figure
AriPotta
  • AriPotta
you already figured out that B = 187
anonymous
  • anonymous
oh times 11. ok
anonymous
  • anonymous
yes, ma'am
anonymous
  • anonymous
ok. ill correct that.
anonymous
  • anonymous
done
AriPotta
  • AriPotta
what's the second figure?
anonymous
  • anonymous
triangular prism
AriPotta
  • AriPotta
yep, and what's the perimeter of the base?
anonymous
  • anonymous
umm, let me add,
anonymous
  • anonymous
42?
anonymous
  • anonymous
btw in the first pic dont include the floor/ base of figure since you dont need to paint that :P
anonymous
  • anonymous
in^2?
anonymous
  • anonymous
ok timo:)
AriPotta
  • AriPotta
the base of a triangular prism is a triangle, you should get 36 as the perimeter
AriPotta
  • AriPotta
and i think timo is talking about number 6? we're only on number 2
anonymous
  • anonymous
um,is it not 9+12+9+12?
AriPotta
  • AriPotta
no, because it's a triangle, not a square or rectangle. so add up 9, 12, and 15
anonymous
  • anonymous
oh. ok.. i get it:)
anonymous
  • anonymous
let me write that
anonymous
  • anonymous
done
anonymous
  • anonymous
b would be..umm..let me calculate..
anonymous
  • anonymous
um, 54?
AriPotta
  • AriPotta
yep :)
anonymous
  • anonymous
yay! im finally getting it! tnx to the awesome ari! i mean 296!
anonymous
  • anonymous
ok,let me write 54 down.
anonymous
  • anonymous
done
anonymous
  • anonymous
ok, eo,lateral, let me try.
anonymous
  • anonymous
324
AriPotta
  • AriPotta
no. the lateral area would be the rectangles
anonymous
  • anonymous
oh. but are the formu,as not the same or smthing?
AriPotta
  • AriPotta
no, they're not. that formula was for a rectangular prism. this is a triangular prism
anonymous
  • anonymous
because it too asks for the lateral area of the triang. prism
anonymous
  • anonymous
can u plz explain for the triang prism?
AriPotta
  • AriPotta
just find the areas for each of the rectangles and add them together
anonymous
  • anonymous
oh. um, let me try,
anonymous
  • anonymous
438?
AriPotta
  • AriPotta
no
anonymous
  • anonymous
aah! um, area of a triangle is bh,yes?
AriPotta
  • AriPotta
you're not trying to find the area of the triangle. you're finding the areas of each of the rectangles
AriPotta
  • AriPotta
and area of a triangle = bh/2
anonymous
  • anonymous
ohh. so im actually finding the area of rectangles as those a re the laterals'/sides?
AriPotta
  • AriPotta
yes.
anonymous
  • anonymous
ohh. ok,once more..
anonymous
  • anonymous
um, was it more or less than my last answ er?
AriPotta
  • AriPotta
...more.
anonymous
  • anonymous
372?
AriPotta
  • AriPotta
311, i gotta do some chemistry soon. no.
anonymous
  • anonymous
you have to include the 15?
anonymous

im using a calculator.
AriPotta
  • AriPotta
i'm using one too. it's 330
anonymous
  • anonymous
the first i said 264
anonymous
  • anonymous
i put 22*15 into web22.0calc
AriPotta
  • AriPotta
maybe you should use a different calculator

  • anonymous
o yea! just used google's
AriPotta
  • AriPotta
so what's the area of that last rectangle?
anonymous
  • anonymous
um,the first one was 264. the second 330?
AriPotta
  • AriPotta
what's the area of this rectangle...
1 Attachment

9 x 12?
AriPotta
  • AriPotta
9 x 22...
anonymous
  • anonymous
umm 198
AriPotta
  • AriPotta
yes. so what's 198 + 330 + 264?
anonymous
  • anonymous
um 762
AriPotta
  • AriPotta
792
anonymous
  • anonymous
ok. ill let you alone now. tnx ill search for someone elses hellp if u like
AriPotta
  • AriPotta
i was gonna finish helping you with this one. you still have to find total surface area
anonymous
  • anonymous
o yea
AriPotta
  • 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
  • AriPotta
triangles*
anonymous
  • anonymous
um... let me se..
anonymous
  • anonymous
is 12 tthe base?
AriPotta
  • 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
  • anonymous
ok. um
anonymous
  • anonymous
900
AriPotta
  • AriPotta
yes!
AriPotta
  • AriPotta
does that make sense? what we did?
anonymous
  • anonymous
finally. tnx,ari:) ill stop botheringn u now
anonymous
  • anonymous
um,yes u believe so

hi jake its only 4 probs
anonymous
  • anonymous
okay 296:) tnx for ur help
AriPotta
  • AriPotta
no problem :) make sure you tell him you've done one and two on the second link
AriPotta
  • AriPotta
well, i guess i just did lol. nvm
anonymous
  • anonymous
okay. jake, ive done one and two on the second link:D
anonymous
  • anonymous
what are the P and B things? Help me help you...
anonymous
  • anonymous
and i need not do the bonus
anonymous
  • anonymous
ok. lol p isperimeter of base
anonymous
  • anonymous
b is area of base
anonymous
  • anonymous
And you're up to # 3 on the 2nd link, as sayeth @AriPotta ?
anonymous
  • anonymous
yes
anonymous
  • 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
  • anonymous
i want to try and talk old fashionedly noe lol
anonymous
  • anonymous
jake pls can u work them out and explain asnu gi along? please?
anonymous
  • anonymous
its 4 probs
anonymous
  • 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
  • anonymous
ok. letnme add.
anonymous
  • anonymous
20
anonymous
  • 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
  • anonymous
yay! ok, now, b
anonymous
  • 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
  • anonymous
ok,sir
anonymous
  • anonymous
What did you get?
anonymous
  • anonymous
17.2
anonymous
  • anonymous
Jame, Ive to go soon. But, if you leave explanations to thhe three remaining problems,mi will give you a medal.
anonymous
  • 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
  • anonymous
oops s, jake*
anonymous
  • anonymous
Yes,? please. i am begging you. ill rereadmthe explanation so i get them.
anonymous
  • anonymous
itmis 11:00 pm where i amAnd ive to get up early tmrw
anonymous
  • anonymous
please?
anonymous
  • anonymous
i would very much appreciate itnif u droppedoff thenanswersnhere. i really really need them:/
anonymous
  • 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
  • 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
  • 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
  • anonymous
um and the height would be 4.3,yes?
anonymous
  • anonymous
no that's the height of the base side. Height of the prism itself is shown as 9
anonymous
  • anonymous
um, ok 180
anonymous
  • anonymous
that's the 3rd part... lateral side area = 120
anonymous
  • anonymous
oops, 180, sorry!!!!!!!!!
anonymous
  • anonymous
i have to go:/ please:/ have mercy:/
anonymous
  • anonymous
3rd part: lateral side area = 180 4th part: total area = 180 + top + bottom = 180 + 17.2 + 17.2 = 180 + 34.4 = 214.4
