if length of the shortest piece is "L", then the next is 2L, the next is 4L, and the next is 8L.
L+2L+3L+4L+8L = 60
18L = 60

the longest piece is .

Let 1st cut = x ft
2nd cut = 2x ft
3rd cut = 2.2.x = 4 ft
4th cut = 2.2.2.x = 8x ft
then 1st cut + 2nd cut + 3rd cut + 4th cut = 60
substitute length of each cut in, we get
x+2x+4x+8x = 60 = 15x
Then x = 4
The longest piece = 8x = 8.4 = 32 ft
