The problem asks for the integral of the function:

\[
\int \frac{x^2}{1 - x^6} \, dx
\]

### Solution:

1. **Substitution**: Let \( u = x^3 \), so \( du = 3x^2 \, dx \), or equivalently \( \frac{1}{3} du = x^2 \, dx \).

2. **Rewrite the integral**: Substituting into the integral, we have:
   \[
   \int \frac{x^2}{1 - x^6} \, dx = \int \frac{1}{3} \cdot \frac{du}{1 - u^2}
   \]

3. **Recognize the standard form**: The integral is now in a standard form:
   \[
   \int \frac{du}{1 - u^2} = \frac{1}{2} \ln \left|\frac{1 + u}{1 - u}\right| + C
   \]
   where \(C\) is the constant of integration.

4. **Substitute back \( u = x^3 \)**:
   \[
   \frac{1}{3} \int \frac{du}{1 - u^2} = \frac{1}{6} \ln \left|\frac{1 + x^3}{1 - x^3}\right| + C
   \]

Thus, the final answer is:

\[
\int \frac{x^2}{1 - x^6} \, dx = \frac{1}{6} \ln \left|\frac{1 + x^3}{1 - x^3}\right| + C
\]
