The gauge group of the Standard Model, i.e., including electroweak and strong interactions, is SU(3) X SU(2) X U(1) (modulo some technicalities that I don't think matter for this discussion). This is a six-dimensional group, so you need six compactified dimensions in addition to the four dimensions of spacetime that we know in order to construct a Kaluza-Klein/string theory type model that includes all the Standard Model interactions. AFAIK the Calabi-Yau manifolds that are talked about in string theory are examples of six-dimensional compactified spaces that can be used in such a model.
