    Double check box volume please

    Can someone help me calculating the volume of a wedge box, its a wedge like this (ignore the dots):

    .......... -------
    .......... /..........\
    .......... /..............\
    .......... /..................\
    ........../......................\
    .......... -------------------

    This is the side view, the top is 6", bottom is 10" and its 18" wide. The angles on the front and back need to be equal. I think this works out to somewhere around 0.5cf (which is what I am trying to achieve, but I am not certain and want to double check before I decide to start cutting any wood. Its to house a sealed 10" 11Kv.2, mounting depth is 5" I have been searching around online, but can't find a calculator that accepts this shape (and the only ones I can find ask for a partial height, which I have no idea what that is or how to get it)

    Thanks.

    Edit: So the picture looks like crap, but hopefully someone can get an idea of what I am talking about.

    About 0.65 cf with single layer walls. Subtract approximately 0.1 for the sub. So you are pretty close. No harm in going a little bigger.

    I assumed they were external and that the walls were 3/4". Otherwise it would be a perfect 1.

    Thanks both, those dimensions will be external. So sounds like I am just about right for the box size

    Now to just get on and put it together! Thanks again.

    (Top depth + bottom depth) / 2. That's the rectangular prism equivalent.

    Height x Width x Length (Subtracting 1.5 from each measurement for wood thickness)

    Minus sub displacement.

    I don't see the problem.
