Question
In an FCC unit cell a cube is formed by joining the centers of all the tetrahedral voids to generate a new cube.Then the new cube would contain voids as :
Options
A.1 full Tetrahedral void, 1 full Octahedral void
B.1 full Tetrahedral void only
C.8 full Tetrahedral voids and 1 full Octahedral void
D.1 full Octahedral void only
Solution
No. of tetrahedral voids = 8× 
= 1
No. of Octahedral voids = 1 × 1 = 1 (at body center).
= 1 No. of Octahedral voids = 1 × 1 = 1 (at body center).
