The cubic crystal system is also known by which term?

• A. Orthorhombic
• B. Rhombohedral
• C. Monoclinic
• D. Isometric

Answer: (D)

The cubic crystal system is defined by three equal axes and right-angle intersections, giving it the highest symmetry among crystal systems. This symmetry is captured by the term isometric, so the cubic system is also known as the isometric system. The other terms describe different systems: orthorhombic has three unequal axes at 90°, monoclinic has one angled axis, and rhombohedral refers to equal axes with non-90° angles, not the cubic arrangement.
