As the name suggests, it can be constructed by elongating a pentagonal rotunda (''J''6) by attaching a decagonal prism to its base. It can also be seen as an elongated pentagonal orthobirotunda (''J''42) with one pentagonal rotunda removed. ==Formulae== The following formulae for volume and surface area can be used if all faces are regular, with edge length ''a'':〔Stephen Wolfram, "(Elongated pentagonal rotunda )" from Wolfram Alpha.
