Step 1 :Find the intersection points of the function \(f(x) = x^2 - 2\) and the horizontal line \(y = 6\) to determine the bounds of integration: \(x = \pm 2\sqrt{2}\)
Step 2 :Integrate the area of the square cross-sections along the x-axis: \(\int_{-2\sqrt{2}}^{2\sqrt{2}} (8 - x^2)^2 dx = \frac{2048\sqrt{2}}{15}\)
Step 3 :\boxed{\text{Final Answer: The volume of the solid is approximately } 193.087 \text{ cubic units}}
