Solid Figures
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 (cm^{3}) and cubic metres (m^{3}).
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 cm^{2}) and square metres (or m^{2}).

Problems on right circular cylinder. Here we will learn how to solve different types of problems on right circular cylinder. 1. A solid, metallic, right circular cylindrical block of radius 7 cm and height 8 cm is melted and small cubes of edge 2 cm are made from it.

We will discuss here about the volume and surface area of Hollow Cylinder. The figure below shows a hollow cylinder. A cross section of it perpendicular to the length (or height) is the portion bounded by two concentric circles. Here, AB is the outer diameter and CD is the

A cylinder, whose uniform cross section perpendicular to its height (or length) is a circle, is called a right circular cylinder. A right circular cylinder has two plane faces which are circular and curved surface. A right circular cylinder is a solid generated by the

A solid with uniform cross section perpendicular to its length (or height) is a cylinder. The cross section may be a circle, a triangle, a square, a rectangle or a polygon. A can, a pencil, a book, a glass prism, etc., are examples of cylinders. Each one of the figures shown

The cross section of a solid is a plane section resulting from a cut (real or imaginary) perpendicular to the length (or breadth of height) of the solid. If the shape and size of the cross section is the same at every point along the length (or breadth or height) of the
