The Augmented triangular prism is a combination of Triangular prism ,and a Square pyramid.It contains two squares ,and six triangular faces is the Johnson solid  .{Johnson solids are the convex polyhedra having regular faces and equal edge lengths (with the exception of the completely regular Platonic solids, the "semiregular" Archimedean solids, and the two infinite families of prisms and antiprisms).}

    We can construct the Triangular prism first ,and a Square pyramid on one of the square face of the Triangular prism.
