Editing Elongated square pyramid (section)

== Construction ==
The elongated square pyramid is a [[Composite polyhedron|composite]], since it can constructed by attaching one [[Equilateral square pyramid|equilateral square pyramid]] onto one of the faces of a [[Cube (geometry)|cube]], a process known as [[Elongation (geometry)|elongation]] of the pyramid.{{r|timofeenko-2010|rajwade}} One square face of each parent body is thus hidden, leaving five squares and four [[equilateral triangle]]s as faces of the composite.{{r|berman}}

A convex polyhedron in which all of its faces are regular is a [[Johnson solid]], and the elongated square bipyramid is one of them, denoted as <math> J_{15} </math>, the fifteenth Johnson solid.{{r|uehara}}
