So, let's let w be the length of the first piece of the board.
(I was going to do l (small L) but it's too hard to see on computers)

second piece is 2w since it's twice the length of first.
third piece is 6w, since it's six times longer than the first.
and these three pieces were one one 180ft board, therefore, that means:
w + 2w + 6w = 180

now let's solve for w (length of first piece)!
w + 2w + 6w = 180
7w = 180
w = 180/7 ≈ 25.71ft

Therefore, the first piece of the board would be approximately 25.71ft.
