Calculate the volume of an fcc unit cell interms of the atomic radius
The volume of an FCC (face-centered cubic) unit cell can be calculated using the formula:
V = a^3
where a is the lattice parameter, which is equal to 2√2 times the atomic radius (r) in the case of an FCC unit cell.
Therefore, the volume of an FCC unit cell in terms of the atomic radius (r) is:
V = (2√2r)^3 = 16√2r^3
