Perfect Cube Numbers (Part 1)

This lesson introduces perfect cube numbers by exploring the properties of cubes. It explains how a cube is a 3-dimensional solid with square faces and how unit cubes can form a larger cube. The lesson uses a cube with dimensions 4x4x4 to demonstrate that 64 unit cubes are needed to form it, illustrating that 64 is a perfect cube number.
