उत्तर
The correct order of the packing efficiency in different types of unit cells is fcc > bcc > simple cubic.
Explanation:
Packing efficiency in different types of unit cells can be tabulated as
| Unit cell | Packing efficiency |
| fcc | 74% |
| bcc | 68% |
| Simple cubic | 52% |
Hence, correct order is fee (74%) > bee (68%) > simple cubic (52%).
