What is the lattice constant for FCC crystal having atomic radius 1.47

1.	What is the lattice constant for FCC crystal having atomic radius 1.476 Å?(a) 1.476 Å(b) 4.1748 Å(c) 5.216 Å(d) 0
Answer» Right choice is (b) 4.1748 Å To explain I would say: Radius=1.476 Å or 1.476 × 10^-10 m Lattice constant for FCC = 4r/√2 Lattice constant = 4.1748 Å.
