The following figure shows the representation of faces, vertices and edges in a rectangular prism?įrom above we can see that there are strong similarities between the shape and properties of a cuboid and a rectangular prism. How many vertices does a rectangular prism have? It has 8 vertices In other words, the meeting point of a pair of sides of a polygon is called its vertex. Vertices – Points of intersection of edges of a polyhedron are known as its vertices. How many edges does a rectangular prism have? It has 12 vertices It is similar to the sides we have in 2D shapes. In other words, an edge is a line segment on the boundary joining one vertex (corner point) to another. How many faces does a rectangular prism have? It has 6 faces.Įdges – Line segments common to intersecting faces of a polyhedron are known as its edges. Every side has two dimensions, be it a length and a breadth, or a breadth and a height or a length and a height. For example, observe one side of your room or that of a Rubik’s cube. In other words, a face refers to any single flat surface of a 3D shape. Before, that let us recall what we mean by faces, vertices and edges.įaces – Polygons forming a polyhedron are known as its faces. Let us now discuss about the faces, vertices and edges of a rectangular prism. The following figure gives an idea of a 3 dimensional shape and its attributes. These attributes are faces, vertices and edges. It is important to understand here that any 3 dimensional shape has three integral attributes. For example, the laptop, our rooms, mobile phones, ice cream, tennis balls, etc. In our everyday lives, we come across many solid shapes.
In other words, they are solid objects and these objects have fixed shapes and sizes.
This means that unlike two-dimensional shapes, three-dimensional shapes have thickness or depth. 3 Dimensional shapes or 3D shapes are the shapes that have all the three dimensions, i.e. In geometry, a three-dimensional shape can be defined as a solid figure or an object or shape that has three dimensions – length, width and height.
