• # question_answer A match box shows A)  monoclinic geometry B)  cubic geometry C)  orthoorhombic geometry D)  none of these

In match box the length, breadth and height are not same but all the face angles are of${{90}^{o}}$. Hence, it shows orthorhombic geometry for which $a\ne b\ne c$ and $\alpha =\beta =\gamma ={{90}^{o}}$.
