Answer 1

what you need is a formula to find out the volume of the right prism.

Answer 2

Do u know it ?

Answer 3

Volume of a rectangular prism is V = (base area) (height).

What are the length and width of the base?
What is the height?
What is the volume?

Answer 4

i have, but you could find it out if you do some research.

Answer 5

in this case, it's the right prism @mathmale

Answer 6

Is it L*W*H ?

Answer 7

@knov: This discussion is between Rekt2 and myself. Contribute if you can; otherwise please stay on the sidelines. Thank you.

Rekt2: Yes!

Answer 8

okay, i was trying to do some teamwork. nvm

Answer 9

Haha

Answer 10

Come on, let's solve this problem.

Answer 11

Ok mathmale ^

Answer 12

The volume of the right rect. prism is V = L W H.
The base is L W. What's that?
The height is ... ?

The volume is ... ?

Answer 13

Which mean if im doing L*W*H it should come like this \[5*3=15 * 8 = 120\]

Answer 14

Right ?

Answer 15

Answer 16

You have the correct outcome. However, there's a technicality here (but an important one):
\[5*3=15 * 8 = 120\]... should not be written that way. You are to calculate 5*3 first,
and then move downward to the next line before you do the final mult (15 times 8).\[3*5=15. ~Right.\]

Answer 17

\[Then:~15*8=120\]

Answer 18

Oh,but that's the same thing i did

Answer 19

Must provide units of measurement. What are you measuring / calculating here?
What is the correct unit of measurement for that quantity?

Answer 20

No, not the same thing. Your \[5*3=15 * 8 = 120\]

Answer 21

says that 5*3 equals 120. Is that correct?

Answer 22

Oh, i get it now

Answer 23

So, use a separate line for each step of your calculations.

Answer 24

So it should look like this \[5*3= 15\] \[15*8 = 120\]

Answer 25

Units of measurement?

Answer 26

Yes

Answer 27

units of measurement still missing. Your volume is 120 what?

Answer 28

\[120\]in

Answer 29

120 in *

Answer 30

Do we measure volume in inches?

Answer 31

I think so ?

Answer 32

Or do we ?

Answer 33

We measure length in inches. My pencil is 4 3/4 inches long.
We measure area in ... ?
We measure volume in ... ?

Answer 34

i think i'm doing something wrong ?

Answer 35

No. You've just forgotten that volume is measured in cubic inches, or \[inch^3~or~inches^3~or"cubic~inches."\]

Answer 36

What is the volume of your rright rect. prism?

Answer 37

Right*

Answer 38

120 in\[120 inches ^{3}\]

Answer 39

Much better. That's it. You're done. You could also type "inches^3."

Answer 40

Oh,ok ,thanks
