    Before you learn about solid figures, learn about the circle, square, triangle and other such polygons (polygons = closed plane structures with many sides)
    Unlike plane figures, solid figures are not flat, they have a three dimensional look.
    Sphere, cone, cylinder are examples of solid figures. But you must be able to classify them according to the number of faces or their look.
    Some solid figures have curved surfaces also. Example is the cylinder. The flat surfaces are called FACES.
    The faces of a cone and cylinder are circles as you can imagine.

    Generally, we can say, figures that are not flat like plane figures are called solid figures.

    The solid figures have vertices, edges, faces
    A cube has 6 faces, 12 edges and 8 vertices.
    The line segment where two faces meet is an edge.
    The point where edges meet is a vertex.

    Now can you explain the number of vertices, edges and faces in the case of a prism ?

    A cone has no edges, but the point where the surface of the cone ends is called the vertex of the cone. A cylinder has two faces; the faces don't meet, so there are no edges or vertices.
