A tetradecahedron is a polyhedron with 14 faces. There are numerous topologically distinct forms of a tetradecahedron, with many constructible entirely with regular polygon faces. A tetradecahedron is sometimes called a tetrakaidecahedron. No difference in meaning is ascribed. The Greek word kai means 'and'. There is evidence that mammalian epidermal cells are shaped like flattened tetrakaidecahedra, an idea first suggested by Lord Kelvin. The polyhedron can also be found in soap bubbles and in sintered ceramics, due to its ability to tesselate in 3D space.

  • Un tetradecàedre o tetradecaedre és un políedre que té catorze cares. Hi ha moltes formes topològicament diferents de tridecàedres, moltes de les quals construïbles completament amb cares de polígons regulars. Un tetradecàedre s'anomena de vegades tetrakaidecàedre (o tetrakaidecaedre). No hi ha cap diferència en el significat. L'arrel grega significa 'i'. Hi ha evidència que les cèl·lules mamíferes de l'epidermis tenen forma de tetrakaidecaedres plans, una idea suggerida per primer cop per Lord Kelvin. (ca)
  • Ein Tetradekaeder ist ein konvexes Polyeder, das sich aus vierzehn Flächen zusammensetzt. Bekannt ist z. B. das unten gezeigte chirale Tetradekaeder, das durch Abstumpfen eines Cubus simus entsteht und wie dieses eine Umkugel besitzt. Es besteht aus acht unregelmäßigen, aber achsensymmetrischen Fünfecken sowie zwei Quadraten und hat 16 Ecken und 24 Kanten. (de)
  • Στη στερεομετρία, τετραδεκάεδρο λέγεται ένα πολύεδρο που έχει δεκατέσσερις . Υπάρχουν πολυάρυθμα τοπολογικώς σαφή τετραδεκάεδρα και πολλά από αυτά κατασκευάζονται εξ ολοκλήρου με κανονικά πολύγωνα ως έδρες. (el)
  • Un tetradecaedro o tetracaidecaedro es un poliedro de 14 caras. Puede tomar numerosas formas topológicamente distintas, y muchos de ellos están formados únicamente de caras que son polígonos regulares. (es)

  • Un tétrakaidécaèdre, ou tétradécaèdre, est un polyèdre possédant 14 faces. Il en existe de nombreuses formes topologiquement distinctes, dont beaucoup ne comportent que des faces en forme de polygone régulier. (fr)

  • 十四面体(じゅうしめんたい、じゅうよんめんたい、Tetradecahedron)は、14つの面からなる多面体。十二角柱や十三角錐は多くの人が知る十四面体である。 (ja)
  • 십사면체(十四面體)는 면이 14개인 다면체를 말한다. 대표적으로는 육팔면체와 깎은 정육면체와 깎은 정팔면체 (또는 깎은 엇삼각기둥이라고도 한다) 그리고 즉 360° 평면인 이 있다. 그 외에도 과 , , 등이 있다. (ko)
  • 在幾何學中,十四面體是指由十四個面組成的多面體,而每個面都是正多邊形的十四面體有時稱為半正十四面體。 半正十四面體並不唯一,不像半正五面體、半正七面體只有一個,半正十四面體有四個,分別是截半立方體、截角立方體、截角八面體和正十二角柱。除了半正十四面體之外,十四面體可以是十三角錐、雙七角錐、七方偏方面體、正三角帳塔柱、同相雙三角帳塔、三側錐三角柱、截對角六方偏方面體、側帳塔截角四面體、恰薩爾十四面體等多面體。在凸十四面體中,有1,496,225,352種不同拓樸結構的十四面體具有至少9個頂點。 (zh)
