Question

HELP!!!!!

Answer 1

Hey, what will it be?

Answer 2

B is denoted as point and also as the area in this problem which could be confusing at first. Where do you see the base of the prism?

Answer 3

the base is points b & a & e

Answer 4

and one other point that's not labeled right?

Answer 5

yes, and how do i find the base

Answer 6

well sounds like you found it then.. the area is just the surface of area of the shape it has..

Answer 7

i don't understand how i already found it @daniel.ohearn1

Answer 8

The base of the prism is the bottom of it right? So you were saying it's the shape shape with corner points A,B,and E?

Answer 9

Please look at the dimensions of the base. What is the length of the base? What is the width? What is the area? Show your work, so that you can describe it later.

Answer 10

A to B is 3.5

Answer 11

E to A is 3

Answer 12

I view the distance from A to B as 4. Please show how you obtained 3.5.

Answer 13

so the base is 10.5

Answer 14

What is A to B skttles?

Answer 15

i got 3.5 because the E to A line is not all the way touching the 4

Answer 16

Please, would you answer questions a bit more linearly? I'm asking you how long the base is; you believe it's 3.5 and I believe it's 4. We must determine why we have different answers. We're not ready to find the aera of the base until we've done that. Notice that daniel is asking you the same question. What is the distance from A to B?

Answer 17

Ask Daniel what he thinks.

Answer 18

so @daniel.ohearn1 what do you think B to A is

Answer 19

I believe Daniel would KNOW, not think, what this distance is.

Answer 20

Perhaps you could persuade him to explain how to find this distance.

Answer 21

B to A is the distance between the points (4,3,1) and (0,3,1)

Answer 22

oh i see now sorry guys

Answer 23

it is 4

Answer 24

so the base is 12

Answer 25

We don't need further critical speculation of the graph to see that this right, and numerically verdant.

Answer 26

You are right there

Answer 27

ok so when i put in the box show I write " A to B is 4 & E to A is 3. To get the base I multipled the Length & Width and i got 12

Answer 28

"so the base is 12" ... Well, not quite. It's the AREA of the base that is 12. Since this whole problem is about areas, it was worth it to me to tell you this.

Answer 29

Now you have a couple more areas to find in pretty much the same way.

Answer 30

ok

Answer 31

Look at the ends of this prism: They're triangles. How would you find their area (same for each end)?

If you know the distance from A to B (which you now do), and y ou know the area of the ends, how would you go about tfinding the volume of this prism? Discuss this with Daniel, please.

Answer 32

I must confess I forgot that the goal of this problem is to find the volume of the prism, not the total surface area.

But if you can answer my lastest question, you'll still be on track to find the volume.

Answer 33

do you agree that the height is 4

Answer 34

Yes.

Answer 35

What is the base of the triangle?
If the height is 4, what is the area of the triangle?

Answer 36

ok do you know what the formula for volume is i forgot

Answer 37

Yes, I do, but I strongly encourage you to look that up yourself. Google "volume of a rectangular prism."

Answer 38

ok

Answer 39

A more pressing question is: What is the area of the triangular end of the prism?

Answer 40

If you find the area, then multiplying it by the length of the prism (4) will give you the volume of the prism. Volume = (base)(height).

Answer 41

v=lwh/3 is that correct

Answer 42

What if you had a volume LWH? What would that prism look like?

Answer 43

so guys is this correct

Answer 44

is this correct
@daniel.ohearn1
@mathmale

Answer 45

V does not equal lwh/3 lwh would look like a rectangular box right?

In two dimensions lw is a rectangle but what we have is triangular prism right?

Answer 46

no

Answer 47

if you scroll to the top of the page you will see it is a Right rectangular pyramid

Answer 48

Agreed. And the ends of this pyramid are triangles, and the triangles are right triangles.

Answer 49

It actually tells u its a trianglular prism and what do you know about the area of a triangle?

Answer 50

We already know that the base has length 4. The height is also 4. what is the width of the base?

Answer 51

thanks so much guys your the best

Answer 52

Very happy you've found the answer. And thank you very much Daniel, for y our helpful input.

Answer 53

Right, if you have no more questions about it, skittles_..
