Answer

**Step-by-Step Solution:**

1. **Understand the Definition of a Cube**: A cube is a three-dimensional geometric shape that has six faces, all of which are squares.

2. **Identify the Properties of a Cube**: One of the key properties of a cube is that all its edges (the line segments where two faces meet) are of equal length.

3. **Evaluate the Statement**: The statement in question is "A cube has all edges equal." Given the definition and properties of a cube, we can confirm that this statement is indeed correct.

4. **Conclude the Answer**: Since all edges of a cube are equal, we can state that the statement is true (T).

**Final Answer**: True (T)
