Answer:
3.14 residues
Explanation:
This kind of sheets has the particularity that the distance between adjacent residues is 3.5 Angstroms. Furthermore, there are two residues per cycle.
Hence, we can calculate easily the number of residues in a segment, by using the expression:
Nr = (256 Å) / (3.5 Å/residue) = 3.14 residues
I hope this is useful for you
