Answer

To solve the problem of identifying the number that is different from the others among the given numbers (8, 64, 125, and 28), we can follow these steps:

### Step 1: Identify the numbers given
The numbers provided are:
- 8
- 64
- 125
- 28

### Step 2: Analyze each number
We will check if each number can be expressed as a cube of an integer.

- **For 8**:
\[ 8 = 2^3 \]
This is the cube of 2.

- **For 64**:
\[ 64 = 4^3 \]
This is the cube of 4.

- **For 125**:
\[ 125 = 5^3 \]
This is the cube of 5.

- **For 28**:
28 cannot be expressed as a cube of any integer.

### Step 3: Conclusion
From the analysis, we see that 8, 64, and 125 are all perfect cubes, while 28 is not. Therefore, the number that is different from the others is 28.

### Final Answer
The number which is different from the others is **28**.
