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

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.

How many edges does a cuboid have ?

Solid having only line segments as its edges is a

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.

Assertion : If the areas of three adjacent faces of a cuboid are x, y, z respectively then the volume of the cuboid is sqrt(xyz). Reason : Volume of a cuboid whose edges are l, b and h is lbh units.

The areas of three adjacent faces of a cuboid are x, y and z. If V is the volume of the cuboid, then which one of the following is correct ?

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.

Base and lateral faces any face of a cuboid may be called the base of the cuboid.In that case the four faces which meet the base are called the lateral faces of the cuboid.
