Mensuration : Length, Area, and Volume

Welcome to the lessons that give firm foundation in measuring perimeter, area, and volume.

To measure a length, area, or volume one of the following methods is used.

 •  Measurement by Superimposition, Calculation and Equivalence

 •  Equivalence by infinitesimal pieces, and Cavalieri's Principle

Once the above is understood, the formula for perimeter, area, and volume of 2D and 3D shapes are provided.

Start learning the exceptional discourse that derive the formulas of mensuration.
