Answer 1

@Hero

Answer 2

@timo86m

Answer 3

i got 56 as p
187 as b
lateral as 672
total as 706
correct?

Answer 4

Number one.

Answer 5

i got 1046 for total

Answer 6

how? i keep getting that wrong..

Answer 7

surface area of a rectangular prism = Ph + 2B

56(12) + 2(187) = 1046

Answer 8

i did 56 x 12 x + 2 x 17

Answer 9

oh. one EIGHT seven. howd u get that?

Answer 10

but 187 is B lol

Answer 11

area of the base... 17 x 17?

Answer 12

1 is easy just add up the sides of the figure

Answer 13

you already figured out that B = 187

Answer 14

oh times 11. ok

Answer 15

yes, ma'am

Answer 16

ok. ill correct that.

Answer 17

done

Answer 18

what's the second figure?

Answer 19

triangular prism

Answer 20

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

Answer 21

umm, let me add,

Answer 22

42?

Answer 23

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

Answer 24

in^2?

Answer 25

ok timo:)

Answer 26

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

Answer 27

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

Answer 28

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

Answer 29

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

Answer 30

oh. ok.. i get it:)

Answer 31

let me write that

Answer 32

done

Answer 33

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

Answer 34

um, 54?

Answer 35

yep :)

Answer 36

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

Answer 37

ok,let me write 54 down.

Answer 38

done

Answer 39

ok, eo,lateral, let me try.

Answer 40

324

Answer 41

no. the lateral area would be the rectangles

Answer 42

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

Answer 43

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

Answer 44

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

Answer 45

can u plz explain for the triang prism?

Answer 46

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

Answer 47

oh. um, let me try,

Answer 48

438?

Answer 49

no

Answer 50

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

Answer 51

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

Answer 52

and area of a triangle = bh/2

Answer 53

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

Answer 54

yes.

Answer 55

ohh. ok,once more..

Answer 56

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

Answer 57

...more.

Answer 58

372?

Answer 59

311, i gotta do some chemistry soon. no.

Answer 60

you have to include the 15?

Answer 61

ok,last try. 444.

Answer 62

what's the area of this rectangle?

Answer 63

yes, 22 x 12, no?

Answer 64

yes, which is...

Answer 65

umm,264

Answer 66

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

Answer 67

umm, 350

Answer 68

594?

Answer 69

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

Answer 70

350

Answer 71

it's 330

Answer 72

and what's the area of this rectangle?

Answer 73

im using a calculator.

Answer 74

i'm using one too. it's 330

Answer 75

the first i said 264

Answer 76

i put 22*15 into web22.0calc

Answer 77

maybe you should use a different calculator

Answer 78

umm,let me see. then..

Answer 79

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

Answer 80

o yea! just used google's

Answer 81

so what's the area of that last rectangle?

Answer 82

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

Answer 83

what's the area of this rectangle...

Answer 84

9 x 12?

Answer 85

9 x 22...

Answer 86

umm 198

Answer 87

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

Answer 88

um 762

Answer 89

792

Answer 90

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

Answer 91

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

Answer 92

o yea

Answer 93

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

Answer 94

triangles*

Answer 95

um... let me se..

Answer 96

is 12 tthe base?
