16.65 feet

Okay, we have three boards that are each 6.85 feet long. If we cut 3.4 feet off one board, that board has:

#6.85-3.4=3.45# feet left

If we cut off 0.5 feet off another board, that board has:

#6.85-0.5=6.35# feet left

So, if we take our three new boards, the total length of plywood left is:

#6.85+3.45+6.35=16.65# feet

Hope this helps!
