how many lengths fit this lengths???

[shadow]

ok well i think this is simple enough but it might be easier if i use a lisp cause later the lengths may vary
i have a length that i need to know the best combo of the following lengths to use
say my total length is 88'-10" or 1066"
and say i have the folowing lengths of lines to fit in this distance
3'-6"
7'-1"
10'-4"
12'-4"
14'-4
ok so how would i go about figureing out what combo of these lengths would fit with the least amount of waste say like each peice only overlaps one another less than 1/2"
if everyone helps everybody the world will be a better place

yes now the length will vary and im trying to figure out if there is less than 1/2" overlap (so say there is a 1/2" overlap) but gives me a a combonation of given lengths to fit on this given total length so that i might reduce waste of materials if everyone helps everybody the world will be a better place
