angled enclosure volume question

[veloglider 10+ year member]

I have just purchased a 15" stereo integrity magnum d2. Minimum enclosed box is 2.5 cubes. I want to build a box that meets the minimum requirements at 2.5 cubes but want to build the box somewhat with the sub face on an angle like 45 degrees. There will be a few inches on the bottom before the angle starts , how do i figure out the cubic feet, i know the formula for a rectangle but this is different? Need help asap

a triangle's area is exactly half of it's width times height. You should remember that from geometry //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Exactly! And if you know the angle and the height you should be able to figure out the depth and the top angle and the hypotenus, etc.

Geometery was my FAVORITE of the math series save Physics with Calc 2! //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
