What is Mensuration?

Mensuration could be defined as the division of mathematics that studies geometric figure calculation and its parameters such as area, length, volume, lateral surface area, surface area, etc is known as mensuration. The subject outlines the principles of calculation and discusses all the essential equations and properties of various geometric shapes and figures that we come across.  It is an important chapter for class 6 students and plays a crucial role in making the concepts clear. 

Mensuration is a subject of geometry. It deals with the size, region and density of different forms both 2D and 3D. Let’s think about 2D and 3D forms and the distinction between them and try learning it  in detail.

Let’s Learn About 2D and 3D Diagrams!

A 2D diagram is a shape made on a plane by three or more straight lines or a closed segment. Such shapes do not have a width or a height. But have two dimensions-length and breadth. Therefore, they are known as 2D shapes. In 2D figures, area (A) and perimeter (P) is to be ascertained. Whereas, a 3D shape  is surrounded by a variety of surfaces or planes. These shapes are often considered robust types. Unlike 2D shapes, 3D shapes have height or depth. They have three-dimensional length, breadth and height/depth and are thus labelled as 3D figures. 3D shapes are made up of many 2D shapes. Commonly known as strong forms, volume (V), curved surface area (CSA), lateral surface area (LSA) and complete surface area (TSA) are used in measuring 3D shapes.

Some Important Terms in Mensuration are:

  • Area (A): Area is called the surface occupied by a defined closed region. 

  • Perimeter (P): Total length of a figure’s boundary is called its perimeter. Perimeter is determined by only two-dimensional shapes or figures. It is a line along the edge of the closed vessel and is represented by P. Its measures are taken in a square unit.

  • Volume (V): The width of the space in a three-dimensional closed shape or surface, like the area by a room or cylinder, is called volume. Volume is denoted by the alphabet V and it is the cubic meter.

  • Curved Surface Area (CSA):  The curved surface area is an area of the only curved surface in a figure, ignoring the base and the top. Such as a sphere or a circle. 

  • Lateral Surface Area (LSA): Total area of a figure’s lateral surfaces is called the Lateral Surface Area. Lateral surfaces are the layers covering the figure.  

  • Total Surface Area (TSA): Calculation of the total area of all surfaces is called the Cumulative Surface Region. For instance, we can obtain the Total Surface Area in a cuboid by adding the area of all six surfaces. 

  • Square Unit: A square unit is simply a one-unit square area. When we quantify some surface area, we relate it to the sides of one block square to know how many units will fit in the respective shape.

  • Cube Unit: A cubic unit is a one-unit volume filled by a side cube. When we calculate the volume of any number, we refer to this cube of side one unit and see how many of these component cubes will fit in the defined closed form.

FAQs on RD Sharma Class 6 Maths Solutions Chapter 20 - Mensuration

1. Why are we studying Mensuration?

Mensuration is a mathematics division where we learn about all kinds of forms and proportions, whether they are 2D or 3D shapes. Circles, triangles, cubes, cylinders and others are some of the very common shapes that we see in day to day lives. Such figures are used to consider the sorts or types of geometric forms that we see in our everyday lives. Geometry also helps in calculating the proportions of certain shapes.

2. What is meant by Solid Mensuration?

Solid mensuration is another term of solid geometry which is a discipline of mathematics where measurements of three-dimensional forms are studied. Length, width and height are the three most important aspects of a solid measurement. The study of various solids is simply known as solid mensuration. It helps in measuring height, length, breadth, volume, area and many other aspects. The chapter is in a detailed manner in RD Sharma solution for class 6 Chapter 20 Mensuration. Vedantu also provides free PDFs. 

3. What is an instance of a plain figure?

Plain figures, for example, squares, triangles and circles are two dimensional. The straight line that forms a plain outline is known as sides. Some common examples of plane figures that we see in everyday lives could be a sheet of paper, a stamp, signboards on the road, a plate or even a chip. Mensuration and its basic concepts are taught in a very easy and interesting manner in Vedantu. The illustrations of the chapter given in RD Sharma are also vast which would help children in clearing their doubts. RD Sharma solution for all classes is available for free at Vedantu.
