MENSURATION

MENSURATION:

Mensuration is a division of mathematics that studies geometric figure calculation and its parameters such as area, length, volume, lateral surface area, surface area, etc. Mensuration deals with the size, region, and density of different forms both 2D and 3D.

WHAT IS A 2DIMENSIONAL SHAPE?

A 2D diagram is a shape laid down on a plane by three or more straight lines or a closed segment. Such forms do not have width or height; they have two dimensions-length and breadth and are therefore called 2D shapes or figures. Of 2D forms, area (A) and perimeter (P) can be calculated.

 WHAT IS A 3DIMENSIONAL SHAPE?

A 3D shape is a structure surrounded by a variety of surfaces or planes. These are also considered robust types. Unlike 2D shapes, these shapes have height or depth; they have three-dimensional length, breadth and height/depth and are thus called 3D figures. For 3D shapes, Volume (V) can be calculated as well as the Total Surface Area (TSA).

These are the following formulas for the 2D shapes:                                                

These are the formulas for Volume and TSA for the 3D shapes:
