Cube and cube root

geometry

Cube and cube root, terms in geometry. A cube is a closed solid figure with 6 equal square faces; adjoining faces are at right angles to each other. If the edge of a cube is of length a, then its volume is a3. Conversely, if we start with a cube a3, then a is called its cube root.
