Find the approximate percentage increase in volume of a cube of side x metre if the percentage increase in its side is 1%.

Explanation

To find the approximate percentage increase in the volume of a cube when the side length increases by 1%, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Problem**:
We have a cube with a side length \( x \) meters. The volume \( V \) of the cube is given by the formula:
\[
V = x^3
