Ok so i just got these new 12"Fusion subs. Lime green and black, straight nasty lookin ok anyways the quesiton. I have to make a box that has atleast a VAS of 4.48 CuFt. ok now i kno vas is volume air space or wat ever and cubic feet but wat i dont get is how i get the 4.48. I tried doing everything i kno (which aint much) and i cant get it to save my life...can someone help???

volume air space is the sum of the width of the box by the length of the box by the height of the box.

You multiply length X height X depth, in inches, and divide that by 1728. That gives you cubic feet. If you have a box that has a slant face, you add the top depth and the bottom depth, divide that by 2, multiply that by height X length, divided by 1728 to get the cubic feet of the box.
