Meaning: A three-dimensional solid shape with flat polygonal faces, straight edges, and sharp vertices.

多面体,具有平坦多边形面、直边和尖顶点的三维立体图形。
Forma sólida tridimensional con caras poligonales planas, aristas rectas y vértices puntiagudos.
多面体。平らな多角形の面、直線の辺、鋭い頂点を持つ三次元の立体図形です。
다면체. 평평한 다각형 면, 직선 모서리, 뾰족한 꼭짓점을 가진 삼차원 입체 도형입니다.

Common polyhedra include cubes, tetrahedra, and octahedra. The five Platonic solids are regular polyhedra where every face is an identical regular polygon. Euler's formula (V - E + F = 2) relates the number of vertices, edges, and faces of any convex polyhedron. The plural is polyhedra or polyhedrons.

常见的多面体包括立方体、四面体和八面体。五种柏拉图立体是正多面体,其每个面都是相同的正多边形。欧拉公式(V - E + F = 2)建立了任何凸多面体的顶点数、边数和面数之间的关系。复数形式为polyhedra或polyhedrons。
Entre los poliedros más comunes se encuentran los cubos, tetraedros y octaedros. Los cinco sólidos platónicos son poliedros regulares cuyas caras son polígonos regulares idénticos. La fórmula de Euler (V - A + C = 2) relaciona el número de vértices, aristas y caras de cualquier poliedro convexo. El plural puede ser poliedros o, en inglés, polyhedra o polyhedrons.
一般的な多面体には立方体、正四面体、正八面体などがあります。五つのプラトンの立体は、すべての面が同一の正多角形からなる正多面体です。オイラーの公式(V - E + F = 2)は任意の凸多面体の頂点数、辺数、面数の関係を表します。英語での複数形はpolyhedraまたはpolyhedronsです。
대표적인 다면체로는 정육면체, 정사면체, 정팔면체가 있습니다. 다섯 가지 플라톤 입체는 모든 면이 동일한 정다각형인 정다면체입니다. 오일러의 공식(V - E + F = 2)은 임의의 볼록 다면체의 꼭짓점, 모서리, 면의 수를 관련짓습니다. 복수형은 polyhedra 또는 polyhedrons입니다.
