An investigation is conducted into a higher-dimensional maximally symmetric inhomogeneous Bianchi type-I string cosmological model. In order to arrive at a deterministic solution, we have to assume Einstein string space metric depends on two variables in all four directions, and these variables are related to the condition: a(x,t) = L b(x,t), where L is a constant, and b(x,t) = f(x).g(t) This allows us to achieve a deterministic answer. g(t) and c(x,t) = h(x).k(t). The relationship between scalar expansion metric potential and shear tension is a straightforward one. In addition to this, the physical and geometrical characteristics of the higher dimensional string model of the universe are dissected.
