We are familiar with the shapes of a cube, cuboid, cylinder, cone and sphere. These
are called solid shapes or 3D shapes. Let us learn something more about these shapes.

Cube: The figure given below is a cube. Some examples of a cube are

• A cube has 6 faces, shown below.
12 edges and 8 vertices.

• All the edges of a cube are
of the same length.

• All its faces are of the

same size.

Cuboid: The figure given below is a cuboid. Some examples of a cuboid are

• A cuboid has 6 faces, shown below.
8 vertices and 12 edges.

• Its opposite faces are
equal.

Cylinder: The figure given below is a cylinder. Given below are some examples
• A cylinder has 3 faces of cylinders.

(1 curved and 2 plane)
and 2 edges.

• Its opposite faces are

equal.

Cone: The figure given below is a cone. Given below are some examples

• A cone has 2 faces (one of cones.
plane and the other

curved).

• It has 1 vertex and 1 edge.
