How many faces does a sphere has

Personalised one to one tutoring that boosts confidence and doubles progress. 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.

In geometry, a face is a flat surface that bounds a solid object. It is defined by points and the lines drawn between them. When several faces are joined together, the space between them assumes the shape of a 3D object. A sphere is a 3D solid object, but it is round. It has no points, vertices, or edges. However, it is a 3D object and is thus often described as having a single curved face corresponding with its curvature.

For example, a cuboid has 6 faces.

A curtain opens on a stage to reveal different shaped animated characters - a sphere, a cube and a pyramid. And who's going to take home the coveted, and totally pointless, prize of, eh… most properties? The faces of the cube are lit up to highlight all six. A judge writes 6 under faces on a score board. Now the edges of the cube are highlighted. Then the judge writes 12 under edges, and the corners of the cube are highlighted next and 8 recorded under vertices. Right, what about corners, or vertices - that's the bits where the edges meet? Time for the mighty, square-based pyramid.

Three dimensional shapes can be picked up and held because they have length, width and depth. Faces are the surfaces on the outside of a shape. Edges are the lines where two faces meet. Vertices or corners are where two or more edges meet.

If the equilibrium angle the From this point on, the national curriculum does not reference vertices, faces and edges explicitly again, so teachers in other year groups will have to continue to use this vocabulary when looking at shape. Note: The linear diameter of Earth is 12, km. A right triangle has one angle of 3 and a hypotenuse of Even Year 1 pupils can begin to engage with properties of shapes in this way if you want to give them a head start!

Formally, a sphere is the set of points that are all at the same distance r from a given point in three-dimensional space. The earliest known mentions of spheres appear in the work of the ancient Greek mathematicians.
