    The affine differential geometry of m-surfaces (m\(\geq 2)\) in a vector space \(V^{m+2}\) with determinant form is developed in a form similar to the equiaffine theory of hypersurfaces of Blaschke and Berwald to which it reduces for surfaces lying in a hyperplane. It is shown that for \(m\geq 3\) all forms depend on two fundamental forms. Centroaffine spheres of codimension 2 are characterized (for \(m=2\) they are ellipsoids).
