Find the approximate change in the volume of a cube of side `x` metres caused by increasing the side by 1%.

Explanation

To find the approximate change in the volume of a cube when the side length is increased by 1%, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the problem**: We need to find the change in volume of a cube when the side length \( x \) is increased by 1%.

2. **Calculate the change in side length**:
- If the side length \( x \) is increased by 1%, the change in side length \( \Delta x \) can be calculated as:
