Explanation

To round off the given numbers to three significant figures, we will follow these steps for each number:

### Step 1: Round off 23.63 m
1. Identify the first three significant figures: **2, 3, and 6**.
2. Look at the digit following the third significant figure (which is **3**).
3. Since **3** is less than **5**, we do not change the third significant figure.
4. Therefore, the rounded value is **23.6 m**.
