The use of integration is used to find the area and volume of solids. Graphical representation of the areas and volumes of solids is represented with the help of examples. The idea behind the area between two curves is mentioned in this tutorial. Formulas for the areas enclosed by two curves are shown with the use of graphical examples.

Area and volume problems are presented with the assistance of examples and theorems. The integral is presented as a series of a generalization of area, mass, volume, sum and total. Volume problems are treated using disk, washer and shell methods. The methods to find the volumes of solids are compared with each other.
