A cube has edges

In geometrya cube [a] is a three-dimensional solid object bounded by six square faces, facetsor sides, with three meeting at each vertex. Viewed from a corner, it is a hexagon and its net is usually depicted as a cross.

It has 6 faces, which are the flat surfaces you see on each side. Imagine each face as a square. The cube has 8 vertices, which are the points where the corners are. Lastly, the cube has 12 edges. These are the lines where two faces meet, like the lines you trace with your finger around the sides of a dice.

Engage your students with our ready-to-go packs of no-prep games and activities for a range of abilities across Kindergarten to Grade 5! Vertices, faces and edges come up a lot in geometry when children are learning about the properties of 3d shapes. Here we explain what each of these mean and how to work out the number of vertices, faces and edges for any shape. We also include the number of edges, faces and vertices of the most common shapes. Vertices in shapes are the points where two or more line segments or edges meet like a corner. The singular of vertices is vertex. For example, a cube has 8 vertices and a cone has one vertex. Vertices are sometimes called corners but when dealing with 2d and 3d shapes, the word vertices is preferred. Wondering if your students have fully grasped vertices, faces and edges? Use this quiz to check their understanding across 10 questions with answers. These can be used to describe 2d and 3d shapes. Although many shapes have straight lines and straight edges, there are shapes which have curved edges, such as a hemisphere and a cylinder. A cube will have 12 straight edges as seen below; 9 are visible and 3 are hidden.

Although many shapes have straight lines and straight edges, there are shapes which have curved edges, such as a hemisphere and a cylinder. For example, a cuboid rectangular prism has 6 faces.

A new KS2 maths challenge every day. Perfect as lesson starters - no prep required! Find out what vertices, faces and edges mean, and how to work out the number of vertices, faces and edges for any shape. There are also examples of the number of edges, faces and vertices of the most common shapes. 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!

A cube has edges

A cube is a region of space formed by six identical square faces joined along their edges. Three edges join at each corner to form a vertex. The cube can also be called a regular hexahedron. It is one of the five regular polyhedrons, which are also sometimes referred to as the Platonic solids. Enter any one value and the others will be calculated. For example, enter the side length and the volume will be calculated. Similarly, if you enter the surface area, the side length needed to get that area will be calculated.
