Re: box building
L x W x H / 1728 = Total volume - when you measure this use internal dimensions to get the internal volume. If your using 3/4 wood, then just measure the outside of the box and subtract 1.5 from L, H, and W. (.75+.75=1.5....get it..)

Take the 5 and you get a box that is 5" wide and 13" tall. now do you L x H x W / 1728 to get the volume of this one. Now the formula to find the volume of a triangle is L x W x H / 2 / 1728. So 4" wide and 13" tall (and whatever long) and divide it in half and then divide it 1728.
Also do angles matter? Say i wanted a box like this shape /_| and not just |_| shaped would the formula still work. I
If the box below is 15" long then...
Box A: 5 x 13 x 15 / 1728 = .56cu'
Box B: 4 x 13 x 15 / 2 / 1728 = .23cu'
Box A + Box B = .79cu'
Hope this helps.
