The Triaugmented triangular prism has one more Square pyramid than the Biaugmented triangular prism.It is also a combination of Square pyramids ,and triangular prism ;and has three Square pyramids ,and one triangular prism.

    The Triaugmented triangular prism contains fourteen triangular faces ; it is also one of the convex deltahedra ;which is composed of 14 equilateral triangles, and is Johnson solid .

    We can construct the Triangular prism first ,and construct three Square pyramids based on the three square faces on the Triangular prism.

   For a triaugmented triangular prism with unit side length, the surface area and volume are
