    What is the cu.ft. of this

    The width is 15.5, These are outside dimensions.
    Usually Im pretty good at this but I'm having a brain fart I guess. Im guessing it is around .58 cu.ft.

    I hope the pic isnt hard to see. Here are the dimensions.
    Height is 12.5"
    Bottom depth is 11"
    Top Depth is 4.5"
    Front Height is 3"

    http://www.the12volt.com/caraudio/boxcalcs.asp has a volume calculator for this type of design!

    I would tell you the interior volume, but you need to list the thickness of the wood!

    3/4 inch mdf. Sorry. That is the site I use. The cal. they have doesnt include the extra dimension I have. The top side which is 4.5 inches. That's why I cant figure it out. In the block for height 2 on the calculator, Would I add the two numbers together and figure it that way? Like in height 2 put 7.5?

    you could separate into a trapezoid & a rectangle....

    a 3x11 rectangle, and then the height of the trapezoid would be 12.5-3 = 9.5

    so you'd have for the trapezoid:

    0.5 * h * (a + b)
    0.5 * 9.5 * (4.5 + 11)

    and for the rectangle, l * w.
    3 * 11

    add those up (0.5*9.5*(4.5+11)) + (3*11) and multiply by the width, 15.5

    that would be the outer width; so for inner you'd have to account for the wood thickness



    best sig of all time

    (((11*3)+(5.75*1.5)+(8.75*5.75*.5))*12.5)/1728
    ((33+8.625+25.15625)*12.5)/1728
    (66.78125*12.5)/1728
    834.765625/1728
