Thought-Process to Discover Knowledge

Welcome to **nub****trek**.

Books and other education websites provide "matter-of-fact" knowledge. Instead, nubtrek provides a thought-process to discover knowledge.

In each of the topic, the outline of the thought-process, for that topic, is provided for learners and educators.

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. *(click for the list of lessons in this topic)*

Measurement Methods

Welcome to the lessons that provide *firm foundation*' in mensuration topics : perimeter, area, and volume. To measure a length, area, or volume one of the following methods is used.

• Measurement by Superimposition

• Measurement by Calculation

• Measurement by Equivalence

Three methods are used to find equivalence.

• Equivalence by infinitesimal pieces

• Equivalence by Cavalieri's Principle (2D)

• Equivalence by Cavalieri's Principle (3D)

Mensuration: 2D Shapes

The topics provide a simple overview of formulas for perimeter and area of

• polygon

• square and rectangle

• triangle

• circle

• quadrilateral

The derivation of these formulas are outlined for students to better understand and retain.

Mensuration: 3D Shapes

The topics provide a simple overview of formulas for perimeter and area of

• cube

• cuboid

• cylinder

• prism

• pyramid

• cone

• sphere

The derivation of these formulas are outlined for students to better understand and retain.

Mensuration with combination of shapes and Solids

The topics provide a simple overview of formulas for part shapes listed below.

• area of segments and sectors of circle

• surface area and volume of frustum

The derivation of these formulas are outlined for students to better understand and retain.
