Width is 17". Can anyone tell me the volume of this enclosure please. These are outer dimensions and the box will be made with 3/4" MDF. I keep trying to break it into two different triangles but I'm just not sure I'm doing it right. So far I've come up with somewhere between 1.2cuft and 1.5 cuft. Thanks for the help!

You can figure them all out knowing only one.

That doesn't work with your previous numbers.

If that's the case, I need to know all three because I can't use whats known to calculate the rest.

the top question mark on the right equals 2". my origianl post should say 10" on top not 8". Very soory I've been trying to figure this out all after noon.

once you come up with the asnwer can you please explain it to me in case I have to adjust any of the sizes. the box is going behind the seat of an MR2 so thats why the funny shape. I have to make the most of what little room I have.

I honestly wouldn't bother porting this box. In a car that small, a sealed enclosure with the right sub would work best in my opinion.

I broke it down just like I did on the picture. Two triangles and a rectangle. The only tricky part is figuring out whether or not you count the thickness of the wood or not and even that isn't all that tricky.
