Mensuration of Solids

Example of solids are: cube, cuboid, sphere, cone, pyramid, etc. Length, breadth, and height are the three dimensions of solid objects.

Volume of Solids

The total space occupied by a solid is called its volume. Volume is measured in cubic units such as cubic millimetres (mm3), cubic centimetres (cm3), cubic metres (m3) etc.

Cube

Definition of a cube

A cube is an object which looks like solid box-shaped that has six identical square faces.

A cube has 6 equal and plane surfaces. All the faces of a cube are square in shape.

In a cube there are 6 plane surfaces. There are 8 vertices and 12 edges.

Two adjoining plane – surfaces meet at an edge.
