Students should be able to describe the faces, vertices, and edges of each shape. This standard focuses on four main 3D shapes: The sphere has the maximum possible volume of all three-dimensional shapes.Describing 3D shapes in kindergarten is now an expectation as it is a key geometry standard.The sphere has the minimum possible surface area amongst all three-dimensional shapes.The points on the surface are equidistant from the centre of the sphere.To calculate the volume of the sphere : 4/3 * pi * (radius)³.To calculate the surface area of the sphere : 4 * pi * (radius)².To calculate the circumference of the sphere: 2 * pi * radius, where pi = 3.14.To calculate the diameter of the sphere: 2 * radius.Surface Area: The area that the outer region of the sphere occupies is known as the surface area of the sphere.This occupied space is termed the volume of the sphere. Volume: Since the sphere is a three-dimensional shape, it also occupies some space.

It is equal to 6.382 times the radius of the sphere. Circumference: A circumference is any great circle with the plane passing through the centre.In other words, the diameter of a sphere can be described as the distance between the two points on the curved surface, and it is mandatory for the points to pass through the centre of the sphere. Diameter: In mathematical form, diameter is equal to twice the radius of the sphere.Let the centre of the sphere be at point O and the point on the curved surface be P, then the radius of the sphere will be equal to OP. The distance between the centre to the curved surface of the sphere is known as the radius. The important features of a sphere are as follows: 1 Some Special Features of SphereĪ sphere is a three-dimensional shape with no edge and vertex. That is why it is called spheroidal in shape. Some examples are balls, eyeballs, planets. There are numerous real-world objects that are spherical in shape.

These radial lines are known as the radius of the sphere and are equidistant from the centre. It has one curved surface.Ī sphere consists of a centre point through which radial lines come out. All other shapes have edges and vertices.

Cylinder: A cylinder has 1 curved face, 2 flat faces, 2 edges, and 0 vertices.Ī sphere is a three dimensional round shaped object.

Cone: A cone has 1 curved face, 1 edge, and 1 vertex.

Sphere: A sphere consists of 0 edges, 0 vertices, and 1 curved face.

Rectangular Prism or Cuboid: A rectangular prism or cuboid has 6 faces, 12 edges, and 8 vertices.

Cube: A cube has 6 faces, 12 edges, and 8 vertices.

Examples of Three-Dimensional Shapes in Detail The three dimensions form the edges of a 3D geometric shape.Ī few examples of three-dimensional shapes are cube, cuboid, sphere, prism, cone, and cylinder. The main features of three-dimensional shapes are faces, vertices, and edges. On the contrary, the two-dimensional shapes do not have width or depth. Three-dimensional shapes refer to the solid shapes or objects that have three dimensions, namely length, breadth, and height. We study the three-dimensional shapes in geometry.
