Answer 2

you there dpalc?

Answer 3

you'll need to find the thickness of prism B.... first...

Answer 4

hmm

Answer 5

the first prism has a thickness of 3

Answer 6

so its not the hypotenuse we are trying to find, is it?

Answer 7

since the problem says they're similar, that means the dimensions are proportional...
can you solve this proportion:

3/5 = x/6.25

Answer 8

lol, thats pre-algebra.

Answer 9

yep... what's x?

Answer 10

3.75, sir.

Answer 11

so that's the thickness of the prism... x=3.75

Answer 12

yes... that is

Answer 13

volume of the prism is then , Volume = (area of the triangle)*(thickness)

Answer 14

so... what's next?

Answer 15

what did you get for the volume?

Answer 16

do you need to find the area of the triangle?

Answer 17

Approximately 58.58.

Answer 18

I mean

Answer 19

58.59

Answer 20

yep... that's what i got...:)

Answer 21

what are the units?

Answer 22

and that's the correct answer on the review.

Answer 23

oh... just some generic unit. so the unit is "cubic unit"

Answer 24

k, next one?

Answer 25

yep.. close shop...
