Q. Number of crystal systems having only $2$ types of bravais lattices $=x$ , number of crystal system having at least two interfacial angles equal $=y$ and number of crystal systems having all the three edge lengths equal $=z$ . Then find the value of $\text{x} \times \text{y} \times \text{z} \text{.}$

Solution:

$x =2$ (Tetragonal, Monoclinic)
$y=6$ (except triclinic all the bravislattices)
$z =2$ (Cubic, Rhombohedral)
$x y z=262=24.00$
