<image>As shown in the , in the right triangular prism, AC⊥BC, AC=4, BC=CC₁=2. If a plane parallel to one of the lateral faces of the triangular prism A₁B₁C₁-ABC is used to cut the prism, such that the two resulting geometric bodies can be assembled into a rectangular cuboid, then the minimum value of the surface area of the cuboid is ___.
