Shapes

Solid shapes

Solid shapes are also called 3-dimensional figures as they have three dimension-- length, breadth and height

Cuboid:  

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

Each face of a cuboid is of rectangular shape.

 If a pencil run along the edges of a cuboid, we get a rectangle.

Cylinder:  

A cylinder has 3 faces, 2 edges and no vertex.

  One face of a cylinder is curved, while the other two are plane shape.

If a pencil run along the face of a cylinder, we get a circle

Cone:

 A cone has 2 faces, 1 edge and 1 vertex.

 One face of cone is curved while the other is plane

 If a pencil run along the face of a cone, we also get a circle

Sphere:  

A sphere has no edge and no vertex

 It has only one curved face
