Question

The number of symmetry elements in a cube are:

• A. 13
• B. 9
• C. 1
• D. 26

Hint:

Symmetry elements include identity, rotation axes, and reflection planes. Memorizing their totals for common shapes (like cubes) is helpful.

Answer 1

The Correct Option is D

A cube has the following symmetry elements:
• 1 identity element.
• 6 planes of symmetry.
• 3 axes of twofold rotation.
• 4 axes of threefold rotation.
• 3 axes of fourfold rotation.
Summing these, there are a total of 26 symmetry elements.
