Vertices – Points of intersection of edges of a polyhedron are known as its vertices. In other words, the meeting point of a pair of sides of a polygon is called its vertex. Let us now observe the vertices, faces and edges of different solid shapes. Cuboid We know that a 3D shape ha...
Number of faces plus the number of vertices minus the number of edges always equals 2 This can be written: F + V − E = 2 To find out more about this read Euler's Formula.Try it on the cube:A cube has 6 faces, 8 vertices, and 12 edges, so:6...
Vertices, faces and edges are introduced in the national curriculum in Year 2, and so the following information can be used with pupils throughout primary school years. Even Year 1 pupils can begin to engage with properties of shapes in this way if you want to give them a head start! Wha...

If the number of vertices, edges and faces of a rectangular parallelopiped are denote byv,eandfrespectively , the value of(v−e+f)is View Solution If x, y and z represent the number of faces, number of vertices and number of edges respectively of a polyhedron, then which of the foll...
To determine how many edges, faces, and vertices are present in a sphere, we can follow these steps:Step 1: Understand the Definitions - Vertex: A point where two or more edges meet. In 3D shapes, it is a corne

C根据欧拉公式V - E + F = 2进行验证:12 - 18 + 8 = 2,符合条件。 分析各选项的几何特性: 1. **十棱柱 (A)**:n=10,则边数=3n=30,面数=n+2=12,顶点数=2n=20,与题目数据不符。 2. **五棱柱 (B)**:n=5,边数=15,面数=7,顶点数=10,均不符合。
