I am a bit confused. I have to find the volume of a triangular prism.

Question

B=1/2bh=1/2 (8x3)=12ft

Now I have to find the volume how would I do this with the numbers provided

Answer 1

well, you have to know what h is, right?

Answer 2

sorry. You have the area of the triangular base.

Now you need the length (or height) of the prism.

V = Bh

here, "h" is the height of the prism perpendicular to the base, not the height of the triangular base.

The volume of prisms is always Bh.

Answer 3

Hello Steve.
The Base is 8ft
The Height is 3ft

They are saying in the math problem to find the volume though

Answer 4

Hello Steve.

The second part shows this in my math page:
V=BH= ____ x ______ft_____= ft
I guess I am not sure what to put in the spaces?

I thought Volume of a triangular prism was
V=1/2 b x h x l?

Answer 5

Steve I know that I have to take 12ft x height for the volume

Answer 6

you are correct that

V=1/2 b x h x l

Unfortunately, you have not given a value for l
