Vertex for any two edges that meet at an end-point there is a third edge that also meets them at that end -point . This point of intersection of three edges of a cuboid is called a vertex of the cuboid .

Vertex the fixed point V is called the vertex of the cone.

Vertices points of intersection of edges of a polyhedron are known as its vertices.

Two lines meeting at a point are called -

edges any two adjacent of a cuboid meet in a line segment which is called an edge of the cuboid.

Name the teeth with sharp and pointed edges .

Slant height the length of the line segment joining the vertex to any point on the circular edge of the base is called the slant height of the cone.

Two cubes each of edge 12 cm are joined. The surface area of new cuboid is :

Fill in the blanks to make the following statements true: A cuboid has .......... vertices. A cuboid has .......... edges A cuboid has .......... faces. The number of lateral faces of a cuboid is ......... A cuboid all of whose edges are equal is called a ......... Two adjacent faces of a cuboid meet in a line segment called its ......... Each edge of a cuboid can be obtained as a line segment in which two ......... meet. ......... edges of a cube (or cuboid) meet at each of its vertices. A ......... is a cuboid in which all the six faces are squares. The three concurrent edges of a cuboid meet at a point called the ......... of the cuboid.
