  In this work we construct an effective four-dimensional model by
compactifying a ten-dimensional theory of gravity coupled with a real scalar
dilaton field on a time-dependent torus. The corresponding action in four
dimensions is similar to the action of K-essence theories. This approach is
applied to anisotropic cosmological Bianchi type $VI_{(h=-1)}$ model for which
we study the classical coupling of the anisotropic scale factors with the two
real scalar moduli produced by the compactification process. The classical
Einstein field equations give us a hidden symmetry, corresponding to equal
radii B=C, which permits us to solve exactly the equations of motion. With this
hidden symmetry, then we solve the FRW, finding that the scale factor goes to B
radii. Also the corresponding Wheeler-DeWitt (WDW) equation in the context of
Standard Quantum Cosmology is solved. Bohm's formalism for this cosmological
model is revisited too.
