**Problem 7.9** - Locate the centroid of the pyramid shown by integration.

In the diagram, a pyramid is presented within a 3D coordinate system. The pyramid has a square base and triangular faces converging at an apex. The coordinates are represented by axes labeled \(x\), \(y\), and \(z\).

Key elements:
- The base of the pyramid is shown on the \(xz\)-plane, parallel to the \(x\) and \(z\) axes.
- Dimensions of the base are labeled as \(2a\) along the \(z\)-axis and \(2b\) along the \(x\)-axis.
- The height of the pyramid, from the base to the apex along the \(y\)-axis, is labeled \(h\).
- The shape has been divided into smaller sections to possibly indicate integration steps for finding the centroid.

This problem involves calculating the centroid using integration, which involves dividing the pyramid into elemental volumes, calculating the coordinates for each elemental volume, and then integrating these coordinates over the entire volume of the pyramid.
