Morphology

cubic + inch

The meaning is directly compositional: 'cubic' denotes something relating to a cube (three equal dimensions) and 'inch' is a unit of length, so 'cubic inch' naturally denotes the volume of a one-inch cube. This follows standard measurement word-formation patterns (like 'square meter', 'cubic centimeter') that are cross-linguistically common, so a B1 learner who knows the parts will understand it.

Etymology

Cubic inch comes from a simple picture: imagine a small cube with sides one inch long, and cubic means it is a real cube, not a flat shape. That little cube measures 'volume', so a cubic inch is a way to say how much space something takes.
