Thanks for your contribution. The proposed changes replace an existing implementation of surfaceAreaPyramid() with malformed Javadoc and inconsistent formatting. More importantly, an additional closing brace prematurely terminates the class, leaving subsequent methods outside the class declaration. This introduces compilation errors without adding new functionality. Closing this PR.
