Gyroelongated square cupola
In geometry, the gyroelongated square cupola is one of the Johnson solids. As the name suggests, it can be constructed by gyroelongating a square cupola by attaching an octagonal antiprism to its base. It can also be seen as a gyroelongated square bicupola with one square bicupola removed.
Area and volume
The surface area isThe volume is the sum of the volume of a square cupola and the volume of an octagonal prism,
