Question

Help?
A candy bar box is in the shape of a triangular prism. The volume of the box is 1,200 cubic centimeters.

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)


The height would

Answer 1

do you know formula for volume of the triangular prism ?

Answer 2

V = area of base *height of prism divide 2

this will help you ?

Answer 3

hi Julian - do you wan continue it ?

Answer 4

area of base = 10*20=200 cm^2

Answer 5

:O i love that anime noragami aragoto or something like that

Answer 6

but you can calculi the height from this triangle with hypotenuse =13 and bc.the height halfed the edge with length 10 so there can using pythagora to calculi the height

Answer 7

so than h^2 = 13^2 -5^2

h=sqrt(169-25)

h=sqrt144

h=12

do you understand it ?

Answer 8

Sort of, sorry, went to get something to eat

Answer 9

@jhonyy9 Can I by chance restart it and go over it with you?

Answer 10

yes - wait your question

Answer 11

Alright, where do I start? Ready when you are :)

Answer 12

formula of volume - do you know it ?

Answer 13

How to find the volume?

Answer 14

i have wrote above formula

Answer 15

I dont understand how you are explaining it, sort of new too this

Answer 16

but than you wan calculi just the height of prism so you can calculi it from this design bc. the height halfed the edge with length 10 cm

Answer 17

so 10 x 20?

Answer 18

which would be 200

Answer 19

yes area of base - but you need calculi just the height of prism ?

Answer 20

Yes, I need too calculate the height of the box, then figure out he approximate amount of cardboard used to make the sides of the candy box

Answer 21

so I want to figure out what h is?

Answer 22

do you see this right triangle on your posted image - yes ?

so you can calculi easy using pythagora the height from this triangle without using the violum

Answer 23

the volume - sorry

Answer 24

I see the image , but what is pythagora? Is there a way too use volume?

Answer 25

hypothenuse squared = a^2 +b^2
where a and b are these two sides in a right triangle

you dont know it ? - Pythagora's theorem

Answer 26

No, I haven't learned it yet.

Answer 27

ok - so than you need calculi the height using the volume

Answer 28

So Area of base times the height?

Answer 29

and divide 2

Answer 30

So the area of base times the height would be 200, divided by 2 would be 150?

Answer 31

V=area of base time h /2

2V = area of base *h

h= 2V/area of base

Answer 32

So what would I multiply? 13 and 10?

Answer 33

h=2*1200/200

h=?

Answer 34

h=2*6

h=12

Answer 35

Im confused, sorry.

Answer 36

what is what you dont understand ?

Answer 37

Julian for you is clearly ?

Answer 38

Well, I don't know. Am I multiplying the 13cm or with the base or? I'm on Part A still

Answer 39

ok - from the first step

the volume of a triangular prism is area of base time height divide by 2

V=A*h/2

A=200

V=1200

1200 = 200*h/2

1200 = 100*h divide both sides by 100

12=h

ok ?

Answer 40

so for point B. you need to know the length and width of a cardboard - yes ?

Answer 41

Okay, so what do I start with on Part A, I'm really sorry.

Answer 42

@ganeshie8 please help me what i need doing again here for part A ? thank you in advance

Answer 43

Thank you for your help anyways @jhonyy9

Answer 44

was my pleasure

@robtobey please

Answer 45

Yato what is what you dont understand here ?

Answer 46

I just dont understand how too do it, I'm sorry

Answer 47

what part ?

Answer 48

Just part A, what numbers do I multiply, I just dont know

Answer 49

V=1200 yes ?

Answer 50

area of base =200 how you have got it - yes ?

Answer 51

Where is V?

Answer 52

Or *What* is V

Answer 53

formula of volume

V= area of base time height divide 2

V is volume of this triangular prism

Answer 54

so

V=A*h/2

Answer 55

? So V= 150?

Answer 56

I'm sorry if I'm bothering you

Answer 57

no V is the volume what is given 1200 cm^3
