## Question

The unit cell of aluminum is a cube with an edge length of 405 pm. The density of aluminum is 2.70 g cm^{-3}. The type of unit cell is

### Solution

Face centred cubic

we know that,

= 3.9 = 4

Face centred cubic unit cell contains 4 atom per unit cell, therefore, the given unit cell is face centred cubic unit cell.
