Chemistry - Solid State Question with Solution | TestHub

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