Topological index is a graphic invariant of digital quantity, which can be used by researchers to analyze various physical and chemical aspects of molecules. In this paper, the molecular graph of the benzenoid hydrocarbon structure of benzenoid triangular and benzenoid rhombus are explored. Furthermore, degree-based topological indices including product connectivity Kulli-Basava index, sum connectivity Kulli-Basava index, atom-bond connectivity Kulli-Basava index, geometric arithmetic connectivity Kulli-Basava index, and the reciprocal connectivity Kulli-Basava index are determined
