In geometry, the elongated triangular cupola is one of the Johnson solids (J18). As the name suggests, it can be constructed by elongating a triangular cupola (J3) by attaching a hexagonal prism to its base.
The 92 Johnson solids were named and described by Norman Johnson in 1966.

The following formulae for volume and surface area can be used if all faces are regular, with edge length a:[1]
The dual of the elongated triangular cupola has 15 faces: 6 isoceles triangles, 3 rhombi, 6 quadrilaterals.
