Question

Please help, I need some help quickly. its kinda about area.

Answer 1

A candy bar box is in the shape of a triangular prism. The volume of the box is 2,400 cubic centimeters.

A triangular prism is shown with base of triangle labeled 16 cm, sides of triangles labeled 17 cm, and length of the box equal to 20 cm.

Part A: What is the height of the box? Show your work. (5 points)

Part B: What is the approximate amount of cardboard used to make the sides of the candy box? Explain how you got your answer. (5 points)

Answer 2

Can you guys please help?

Answer 3

covered the pythagorean theorem yet?

Answer 4

it doesn't ring a bell

Answer 5

would the height be 17?

Answer 6

ahemm nope, that's just the "slanted height", not altitude
but you'd want to cover the pythagorean theorem first though
check your book on it

Answer 7

since you'd need it to get the altitude

Answer 8

this is online so I don't have a book

Answer 9

so, that means you're exempted from stydying?

Answer 10

and the lessons didn't cover it

Answer 11

what

Answer 12

I don't remember them talking about these problems

Answer 13

well... then... kinda makes this exericse not applicable then
since you haven't covered it

Answer 14

well can you help or not?

Answer 15

do I know the pythagorean theorem? yes
does that help you? nope

the issue is, the exericse is meant to use it
and thus you'd have to cover that first, how it works, what are the ratios, what are the relations, when it works, when it doesn't

so... you'd need to cover it first I'd think

Answer 16

so, if you haven't covered it, the exercise doesn't apply to you

can someone here do it for you? sure
will that "help" you? depends on what you mean by "help"
if you mean understand it, nope

they'll do it, but you wouldn't know what or why they did

Answer 17

Well I got the jist

Answer 18

Well if you tell him/her what the pythagorean theorem than maybe they will remember it I don't understand why you cant say that it is just a formula this person will probably have to use more in geometry

Answer 19

sigh

Answer 20

oh well it can be blank

Answer 21

X^2 + y^2 = z^2

Answer 22

huh

Answer 23

Thats the theorem

Answer 24

Than you have to split the triangle base in half to find the height

Answer 25

So what is your base?

Answer 26

16

Answer 27

Yes so you have to cut that in half because when you are finding another side of a triangle you need to have a right angle so half of that is?

Answer 28

8

Answer 29

Yep so that will be the base now and what is the other side they give you?

Answer 30

20?

Answer 31

Not quite, for the triangle part

Answer 32

Whats the other side of the triangle?

Answer 33

oh 17

Answer 34

Yes so you have sides 8 and 17 the17 doesn't get cut in half, because its the hypotenuse line, so you can almost call this b^2+h^2=l^2 where b is base h is height, and l will be the hypotenuse, does this make sence?

Answer 35

Or long side for l because hypotenuse is always the longest side in a triangle

Answer 36

@study312

Answer 37

sorry afk

Answer 38

Afk?

Answer 39

Away, From, Keyboard

Answer 40

And does this stuff make sense?

Answer 41

more or less

Answer 42

Okay

Answer 43

If you have a question let me know

Answer 44

what now?

Answer 45

is the height 8?

Answer 46

So b=8 and l=17
So we use this formula b^2 + h^2 = l^2
So we plug in 8 for b and 17 for l
8^2+h^2=17^2

Answer 47

So whats 8^2 and 17^2?

Answer 48

8 x 8 is 64 and 17 x 17 is 289

Answer 49

Yes so now you have 64+h^2=289 how do you isolate to have just h^2 left?

Answer 50

find the square of 289?

Answer 51

are we still figuring out the height?

Answer 52

Nope because you still have the 64 you want to get the 64 to the other side and have h^2 on one sode

Answer 53

Yes were almost done

Answer 54

289 ÷ 2

Answer 55

64+h^2=289 you have to subtract by 64 from both sides so h^2 is alone on one side and 289 minus 64 is? Does this make sense?

Answer 56

yes. 225

Answer 57

So h^2=225 do you know how to get it to just be h=

Answer 58

225 ÷ 2

Answer 59

Nope that would be 2h

Answer 60

If you have the square root what would you do?

Answer 61

well I use a calculator

Answer 62

and its 15

Answer 63

Yes it is

Answer 64

I don't know how to do the second part :(

Answer 65

ok thx

Answer 66

I think it is just area
