Several sets of explicit solutions in the five-dimensional Kaluza-Klein type cosmological models G and Lambda are obtained. The diminishment of extra dimension with the evolution of the universe for the five-dimenonal model is exhibited. The physical properties of the model is exhibited. The physical properties of the models are examined.eninfo:eu-repo/semantics/closedAccessInhomogeneous ModelConstantUniverseConsequencesArticle2482185218810.1088/0256-307X/24/8/009Q3WOS:0002486575000092-s2.0-34547557093Q1
