View Full Version : calculating area

03-25-2006, 04:15 AM
I've been thinking about constructing my own box to maximize the total volume available in my trunk (which isnt much because i have a 00' camaro) and tune it somewhere around 30-35 hz. Right now I have 2 12's, each in a 1 cu foot box and they are struggling in low end output. The box im going to try to build is going to have to be some sort of a custom wedge design so that it can fit down into the rear well of my truck as well as to maximize the space i have back there. This is not going to be easy to calculate the total volume once the box is complete. What are my alternatives for calculating such an irregular box design? Can i take the box somewhere once its complete to have the volume calculated? Any thoughts?

first off, if the box is made up of a combination of squares, rectangles, triangles....if can be figured. divide the box into familiar shapes and do the math from there.

if you have a triangular box: (H X W) / 2
if you have a wedge that may come up a few inches and then angle up, split it into a traingle and a rectangle and calculate from there. look at the pics below. find the volume for the entier shape, including the dotted line part, and calculater from there. if all else fails, you can use packing peanuts and fill the box. take them out and put them into a cardboard box and measure the volume of that.
