Cube Properties: Determining the Number of Faces in a Three-Dimensional Cube

To solve this problem, we'll follow these steps:

• Step 1: Recall the definition and properties of a cube.
• Step 2: Apply these properties to determine the number of faces.

Now, let's work through each step:
Step 1: A cube is a three-dimensional shape with all edges of equal length and all faces square. It is composed entirely of squares from each face being congruent.
Step 2: By definition, a cube has six faces, each of which is a square. When we visualize a cube, we can think of it as having a front, back, left, right, top, and bottom face.

Therefore, the solution to the problem is that a cube has $6$ faces.
