MCQ
In face centered cubic unit cell, what is the volume occupied?
- A$\frac{4}{3} \pi r^3$
- B$\frac{8}{3} \pi r^3$
- ✓$\frac{16}{3} \pi r^3$
- D$\frac{64 r^3}{3 \sqrt{3}}$
✓
Answer
Correct option: C.
$\frac{16}{3} \pi r^3$
(c) : In face centered cubic unit cell, there are four atoms and their volume is given by
$
y=4 \times\left[\frac{4 \pi v^3}{3}\right]=\frac{16 \pi v^3}{3}
$
$
y=4 \times\left[\frac{4 \pi v^3}{3}\right]=\frac{16 \pi v^3}{3}
