A figure made up of a number of plane or curved faces is a solid figure. Bricks, matchboxes, talcum powder containers and rooms are all examples of solid figures. A solid figure has three dimensions while a plane figure has only two dimensions.
Volume of a Solid Figure
The space enclosed by a solid figure is called its volume. The volume of a solid figure is measured in cubic units such as cubic centimetres (cm3) and cubic metres (m3).
Total surface Area of Solid Figure
The sum of areas of the plane or curved faces of a solid is called its total surface area. It is measured in square units such as square centimetres (or cm2) and square metres (or m2).
