Mensuration Formulas: Mensuration is a branch of mathematics that deals with the area, perimeter, volume, and surface area of various geometrical shapes.
It is one of the most important chapters covered in high school Mathematics. Mensuration has immense practical applications in our day-to-day life. It is, for this reason, advanced concepts related to mensuration are covered in higher grades.
Mensuration problems are asked in various government job exams as well, like SSC, Banking, Insurance, etc. So it becomes very important for everyone to understand and memorize the various mensuration formulas for all 2D and 3D geometrical figures. In this article, we will provide you with formulas for area, perimeter, volume, and surface area for all major 2D and 3D geometrical shapes, like square, rectangle, rhombus, circle, cube, cylinder , etc.
Mensuration is the branch of mathematics in which we study the surface area, volume, perimeter, length, breadth, and height of geometric shapes. Shapes can be 2D or 3D in nature. In geometry, a two-dimensional shape or 2D shape is defined as a flat plane figure or a shape that has only two dimensions.
These shapes can be represented in a plane with X-axis and Y-axis. Some common examples of 2D shapes are circle, square, rectangle, parallelogram, and rhombus. A three-dimensional shape or 3D shape is defined as a solid figure or an object that has three dimensions — length, breadth, and height.
We need spatial representation for 3D shapes because they have an extra dimension as thickness or depth. The table below shows the formulas for volume, curved surface area, and total surface area of common 3D geometrical figures:. In mensuration, we come across different terminologies such as area, perimeter, surface area, volume, etc.
We have provided definitions for all these terms so that you can be confident about all the mensuration concepts.
Question 1 : PQRS is a rectangle. The ratio of the sides PQ and QR is 3 : 1. Question 3 : ABCD is a trapezium. Sides AB and CD are parallel to each other. A line parallel to AB divides the trapezium in two parts of equal perimeter.
Question 5 : Find out the height of a cylinder with a circular base of radius 70 cm and volume cubic cm. Ans: Mensuration is commonly referred to as the study of geometry and the formulas that come under it involving the calculation of Area, Perimeter, Volume, and Surface Area of different types of 2D and 3D figures. For the full list of formulas, you can refer to this article.

A: Mensuration deals with the calculation of perimeter, area, volume, and other parameter for 2D or 3D geometric shapes. Geometry is concerned with the properties and relations of points and lines of various shapes. A: 2D mensuration deals with the area, perimeter, volume, and other parameters related to 2D geometric shapes such as square, rectangle, rhombus, circle, etc.
On the other hand, 3D mensuration is concerned with the calculation of volume, curved surface area, lateral surface area, and total surface area of 3D geometric shapes such as sphere, cylinder, cone, etc. Now you are provided with all the necessary information regarding different mensuration formulas.

A 3D shape is surrounded by multiple surfaces or planes. They are represented spatially. For 2D shapes, we measure area and perimeter of figures. For 3D shapes, we measure their volume, curved surface area, and total surface area. Area : Area of a closed 2D geometric shape is defined as the total surface covered by the shape. It is denoted by A. We measure area in m 2 or cm 2. Remember that area is always measured in square units. Perimeter : We define perimeter of a closed 2D geometric shape as the total length of its boundary.
Perimeter is generally denoted by P. It is measured in m or cm. Volume : Volume of a 3D geometric shape is defined as the total space occupied by the object. It is always measured in cube units. Common measurement units are m 3 or cm 3. We denote volume of a solid figure by V. Curved Surface Area : Curved surface area is used for curved objects such as sphere.
It is defined as the total area covered by the curved part of the object. We denote curved surface area by CSA. Since it is a type of area, CSA is also measured in square units m 2 or cm 2. Lateral Surface Area : Lateral surface area is defined as the area occupied by the lateral part of a 3D geometric shape. It is denoted by LSA.
We measure lateral surface area in square units m 2 or cm 2. Total Surface Area : When we combine the curved surface area and the lateral surface area of a 3D geometric shape, we get its total surface area TSA. It is also measured in square units.

Whether it's a sphere or a circle, a rectangle or a cube , a pyramid or a triangle, each shape has specific formulas that you must follow to get the correct measurements. We're going to examine the formulas you will need to figure out the surface area and volume of three-dimensional shapes as well as the area and perimeter of two-dimensional shapes.
Ее черный лоснящийся верх поднимался на двадцать три фута, а сама она уходила далеко вниз, под пол. Своей гладкой окружной формой она напоминала дельфина-косатку, застывшего от холода в схваченном морозом море. Это был ТРАНСТЕКСТ, компьютер, равного которому не было в мире, - шифровальная машина, засекреченная агентством. Подобно айсбергу машина скрывала девяносто процентов своей массы и мощи под поверхностью. Ее секрет был спрятан в керамических шахтах, уходивших на шесть этажей вниз; ее похожий на ракету корпус окружал лабиринт подвесных лесов и кабелей, из-под которых слышалось шипение фреоновой системы охлаждения.
Мистер. Беккер узнал голос. Это девушка. Она стояла у второй входной двери, что была в некотором отдалении, прижимая сумку к груди.
Он не очень-то об этом распространялся. Сьюзан трудно было поверить в такое удачное совпадение. - Его погубило слабое сердце - вот так. Слишком уж удобная версия. Стратмор пожал плечами.
