How many types of Bravais lattices are there?

Which of the following primitive cells show the given parameters?
$a \neq b \neq c, \alpha = \beta = \gamma = 90^{\circ}$

The parameters $a = b = c$ and $\alpha = \beta = \gamma \neq 90^\circ$ belong to which crystal system?

$A$ metal has a $bcc$ structure. If the edge length of its unit cell is $3.04 \ \overset{\circ}{A}$,what is the volume of the unit cell in $cm^3$?

Which of the following crystal systems has $a = b = c$ and $\alpha = \beta = \gamma \neq 90^o$?

Distinguish between
$(i)$ Hexagonal and monoclinic unit cells
$(ii)$ Face-centred and end-centred unit cells.
