Explanation:

A unit - cube is a 3 - D figure with side lengths of 1 unit. Its volume is calculated by \(V = s\times s\times s\), where \(s = 1\) unit, so \(V=1\times1\times1 = 1\) cubic unit. It has 6 square faces, not 4 rectangular faces. It is a 3 - D solid, not a plane figure.

It has a volume of 1 unit.
