Sub Box Volume Help Needed

I'm looking to make a sealed box for a JL Audio 8" W7 that I picked up. I'm going to build it out of 3/4" MDF, and it needs to have a volume of .935 cu ft so when I install the speaker it will be .875 cu ft.
I want to build a wedge type box that will sit on the floor behind the drivers seat, with the speaker mounted on the end facing the center of the truck.

I can find calculators for square/rectangle boxes and for triangle boxes but this one fits neither mold.

Does anyone know of a person who could give me the volume of the box if I provide the dimensions?

Thanks,

Steve

Damn............a little more searching after I posted this and I found it on my own.

Rockford Fosgate® - Woofer BoxWizard

Wedge 2 is the box I'm doing. Perfectly fills the space behind the driver's seat, and gives me the .94 cu ft needed.

Easy, a wedge is the combination of a rectangle and a triangle.

Shoot me the dimensions.

I'm good, using the calculator on Rockford's website saved me.

My box will fit perfectly on the floor behind the drivers seat, and be a "double wedge" design, with the needed volume for my sub, and won't take up any useful space in the truck.

Good to hear you figured it out. Here is the sub box I built for my new colorado. First box I've actually built that I didn't leave MDF sprayed front and back and wrapped it in carpet.

DC 8 tuned to 28hz on 700rms

I just finished building the box tonight, letting it set overnight for the liquid nails to dry.
Carpet will be here tomorrow, so I'm hoping I'll be up and running soon.

I have a JL Audio Slash v1 250/1 amp that will be driving the JL Audio 8" W7 sub in the sealed box. This sub will be replacing my JL Audio 8" Micro Sub that is currently on the floor behind the drivers seat. I'm anxious to see the improvements(if any) that this will produce.
