Mathematics / Mensuration

Mathematics / Mensuration

The length of the total boundary of a figure is called its perimeter. The Metric unit of perimeter is same as the unit of length - Metre.
The perimeter of 2D geometrical figures like quadrilaterals can be obtained by calculating the sum of all the sides of the figure.
The amount of surface covered by an object is called it area. The Metric unit of area is square metre.
In this lesson we will learn to calculate the area and perimeter of many different figures.

The sum of areas of all the faces of a 3D solid figure (both plane and curved) is called its total surface area.
The total amount of space occupied by a 3D solid figure is called its volume.
In this lesson we will learn to find the Surface Area and Volume of many different 3D figures like cube, cuboid, prism, pyramid and many others.
