Check out Mensuration Formulas for 2-D and 3-D shapes below. Now, you may be clear about 2-D shapes and 3-D shapes, but still, for your better understanding, we will bifurcate the mensuration formula tables for both shapes below. These Mensuration formulas are also important for Class 8, 9 10 students, so stay tuned and allow us to help you master your exams. If you are an aspirant of SSC, Bank Exams, or other government exams, you might know that approximately 2-3 questions are asked in the Quantitative Aptitude of SSC CGL, SSC CHSL, SSC MTS, SSC CPO, Delhi Police Constable, Bank Exams paper on mensuration topics. This article is not just important for school-going students but also for those candidates who are preparing for various competitive exams where mensuration holds a huge weightage. Before moving on to the mensuration formulas, let us first understand the difference between 2D and 3D figures. With the help of the mensuration formulas, you will be able to know and calculate the areas, perimeter, volume, total surface area, curved surface area, length, etc of different geometrical figures. Mensuration is all about the measurement of the geometrical figures that come under the category of 2D and 3D shapes. It deals the parameters like shape, length, volume, area, surface area etc. We hope this article gave you required knowledge and information you need.Mensuration Formulas: Mensuration is a branch of mathematics that deals with geometric figures and their measurement. We also discussed the same with different examples and learnt about Euler’s formula. In this article, we discussed basic properties like vertices, faces, and edges of 3-Dimensional shapes. Let’s take one more example of a tetrahedron. It usually works for most of the common polyhedral which we have heard of.įor example, we know that a cube has 6 faces, 12 edges and 8 vertices. It can not be made up of two pieces stuck together, such as two cubes stuck together by one vertex. it can’t be applied for sphere, cylinder or cone. In short, for this formula to work, the shape must not have any holes, and it must not intersect itself. The formula can be used only for closed solids with flat faces. He invented this formula, and hence formula has been given his name. ![]() Euler’s formula has been named after a famous mathematician Leonhard Euler. Let’s see vertices, faces and edges of all known 3-dimensional shapes and see how they differ from one another.Įuler’s formula can be used to find out the relation between vertices, faces, and edges. Consolidated table of vertices, faces and edges of 3-Dimensional shapes Knowing the faces, vertices, edges properties of any objects lays the foundation for various industries such as architecture, interior design, engineering and more. For example, a pyramid has 8 edges, and cuboids have 12 edges. In simple language, an edge is a line segment on the boundary, or an edge is a line segment where two faces meet. In geometry, an edge is a line that joins two vertices of a polygon. For example, a cube has 6 faces, and a cylinder has 3 faces. It is also known as the side of an object. FacesĪ flat surface or a plane region that creates part of the boundary of a solid object is known as a face. More specifically, a point where two or more lines of a polygon meet to form an angle or the corner is called vertex. Vertex is a point where two or more curves, lines or edges of a shape meet. The vertex is written as vertices in plural form, usually denoted by capital letters such as E, P, Q, S, Z, etc. For example, the cube has 6 square faces, 8 vertices, and 12 edges, while the sphere has 0 faces, 0 edges, and 0 vertices. The flat sides of a shape that you touch when you hold a shape are known as faces. Lines around the shape are known as edges. The pointy bits or the corners of a shape where edges meet are known as vertices. Let’s see what does each term mean in very simple language. We can say that vertices, faces and edges are the three main properties that define any 3-dimensional shapes of geometry. They are made up of vertices, faces, and edges. ![]() In this article, we will discuss various aspects of 3-D shapes with definitions and examples. Sometimes they are referred to as solids too. For example, balls, ice-cream cones, books, etc. All objects are of different sizes and shapes. ![]() In our day to day life, we deal with lots of 3-D objects which have length, breadth, and depth. In mathematics, 3-Dimensional shapes are a very important topic of geometry. ![]()
