Question

If a dice is a unit cell, then what type of crystal system is it?

• A. Cubic
• B. Rhombohedral
• C. Monoclinic
• D. Triclinic

Answer 1

The correct option is A

Cubic

We all have seen a dice.

If we look at it carefully,

$\to$ all the sides are of equal length.

$\to$ all the angles are $90{}^{\circ }$.

Therefore $\begin{array}{c}a=b=c\\ \alpha =\beta =\gamma ={90}^{\circ }\end{array}\}Cubic$
