To determine which statement describes a unit cube, we need to understand the definition of a unit cube. A unit cube is a cube where all sides are of equal length, and the length of each side is typically defined as 1 unit in a given measurement system. Let's analyze each option: 1. **A cube that is 4 inches long, 4 inches wide, and 4 inches high**: This cube has all sides equal, but each side is 4 inches, not 1 unit. Therefore, this is not a unit cube. 2. **A cube that is 1 foot long, 1 foot wide, and 1 foot high**: This cube has all sides equal, and each side is 1 foot. While it is a cube, it is not a unit cube in the standard sense, as the unit is typically considered to be 1 unit (not 1 foot). 3. **A cube that is 1 centimeter long, 1 foot wide, and 1 yard high**: This cube does not have equal sides, so it cannot be a unit cube. 4. **A cube that is 5 centimeters long, 5 centimeters wide, and 5 centimeters high**: This cube has all sides equal, but each side is 5 centimeters, not 1 unit. Therefore, this is not a unit cube. None of the options provided describe a unit cube, as a unit cube should have all sides equal to 1 unit in any measurement system (e.g., 1 cm, 1 inch, 1 foot, etc.).
