Philoid · Accepted Answer

The folded ribbon lies between 2 cm and 28 cm. So its length is the distance between 28 cm and 2 cm. It can be about (28-2) = 26 cm. The length of folded ribbon is nearly 26 cm.

The total length of ribbon is about 5×26 cm = 130 cm = 1.30 m. (100 cm = 1 m)

So, the length of the ribbon is 1.25 m-1.35 m.
