Abstract. The present paper contains five sections. First section is introductory and in section second we considered a six-dimensional homogeneous anisotropic model and calculated the scalar curvature with the help of Einstein field equation in f(R,T) gravity theory. In Section 3, we have discussed the solution of Einstein field equation. In Section 4, we have described the physical and geometrical features of the expansion scalar θ, shear scalar σ, average Hubble parameter H, mean anisotropc Am and deceleration parameter q. At last, we have drawn graphs and discussed the variation of pressure p, Hubble parameter H, expansion scalar θ and deceleration parameter q with time t.
