在几何学中，四角化六面体是一种卡塔兰多面体，其为截角正八面体的对偶多面体。

四角化六面体是正方形四边各加一个等腰三角形拼成的正八边形在立体几何中的推广。

一个边长为a的四角化六面体，它的表面积A，体积为。

In geometry, a tetrakis hexahedron (also known as a tetrahexahedron, hextetrahedron and kiscube) is a Catalan solid. Its dual is the truncated octahedron, an Archimedean solid.

It also can be called a disdyakis hexahedron as the dual of an omnitruncated tetrahedron.
