Question

Write the names of any two objects seen in and around us that correspond to the following solid shapes: sphere, cone, cube and cuboid.

Accepted Answer

Below is the shape of a sphere:

Sphere is perfectly symmetrical around its centre. The sphere does not form any edges or vertices and one face.

Therefore, the given shape is a sphere and faces $= 1$ , edges $= 0$ and vertices $= 0$

Example for a sphere: Foot ball, Earth

Cone :

A cone has one plane circular surface i.e. its base and only one curved surface. So, in a cone there is one plane surface and one curved surface. There are one edge and one vertex.

Therefore, the given shape is a circular cone and face $= 1$ , edge $= 1$ and vertex $= 1$

Example: Cone ice-cream, Funnel

Cube:

The above shape is a cube because of equal length, width, height and faces $= 6$ , edges $= 12$ and vertices $= 8$

Example: Sugar cubes, Rubik's cube

Cuboid:

Three-dimensional shapes which consist of six faces, eight vertices and twelve edges can be cube or cuboid.

The primary difference between them is a cube has all its sides equal whereas the length, width and height of a cuboid are different. Both shapes look the same but have different properties.

Therefore, the above shape is a cuboid and faces $= 6$ , edges $= 12$ and vertices $= 8$

Example: Refrigerator, a loaf of bread.
