Question
The base of a solid is the region \( R \) in the first quadrant enclosed by the parabola \( y = x^2 + 2 \), the line \( y = 6 \), and the y-axis, as shown below. Cross sections of the solid perpendicular to the y-axis are regular hexagons, whose area formula is \( A = \frac{3\sqrt{3}}{2} \ell^2 \), where \( \ell \) is the side length. Find the volume of the solid.

The diagram illustrates the region \( R \) in the coordinate plane. It is located in the first quadrant. The boundary of the region comprises:

1. The parabola \( y = x^2 + 2 \).
2. The horizontal line \( y = 6 \).
3. The y-axis.

The region \( R \) is shaded blue and lies under the line \( y = 6 \) and above the parabola \( y = x^2 + 2 \), starting at the y-axis and extending to the point where the line and the parabola intersect. The point of intersection on the graph is at approximately the x-coordinate of 2, where the parabola meets the horizontal line.

Find the volume of the solid by evaluating the integral of cross-sectional areas perpendicular to the y-axis. Each cross-section is a regular hexagon with the area given by the formula provided.
