Total surface area is also measured in square units whereas volume is measured in cubic units. Curved surface area is also known as lateral surface area, and is measured in square units. Under 3-D Figures, we can calculate the total surface area which is equal to curved surface area+ area of top and bottom. Mensuration Formulas for 2-Dimensional FiguresĪ + B + hypotenuse, where the hypotenuse is √A²+B²
Have a look at these mensuration formulas, understand them and learn them by heart. The below table will give you the complete list of areas and perimeters of different 2-D figures such as square, triangle (scalene, isosceles, equilateral, right), trapezium, parallelogram, rhombus, circle, etc. The area of 2-D figures is always calculated in square units and the perimeter is always calculated in units. 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. Mensuration Formulas: Mensuration is a branch of mathematics that deals with geometric figures and their measurement.
