As the name suggests, it can be constructed by elongating a tetrahedron by attaching a triangular prism to its base. Like any elongated pyramid, the resulting solid is topologically (but not geometrically) self-dual. ==Formulae== The following formulae for volume and surface area can be used if all faces are regular, with edge length ''a'':〔Stephen Wolfram, "(Elongated triangular pyramid )" from Wolfram Alpha. Retrieved July 21, 2010.〕 $V=(\backslash frac(\backslash sqrt+3\backslash sqrt))a^3\backslash approx0.550864...a^3$ $A=(3+\backslash sqrt)a^2\backslash approx4.73205...a^2$ If the edges are not the same length, use the individual formulae for the tetrahedron and triangular prism separately, and add the results together. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Elongated triangular pyramid」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
