Explanation

To solve the problem \( 12.8 \times 4.5 \times 2.2 \), we will follow these steps:

### Step 1: Multiply the first two numbers
First, we will multiply \( 12.8 \) and \( 4.5 \).

\[ 12.8 \times 4.5 \]

Calculating this gives:

\[ 12.8 \times 4.5 = 57.6 \]

### Step 2: Multiply the result by the third number
Next, we will take the result from Step 1 and multiply it by \( 2.2 \).

\[ 57.6 \times 2.2 \]

Calculating this gives:

\[ 57.6 \times 2.2 = 126.72 \]

### Final Answer
Thus, the value of \( 12.8 \times 4.5 \times 2.2 \) is:

\[ \boxed{126.72} \]
