Mensuration (Porimiti) Formula in Maths


Mensuration (Porimiti) Formula in Maths. Mensuration is a type of math. That helps us measure and calculate the size and shape of different shapes and objects. It looks at things like shape, size. How much space it takes up, how big it is on the outside, etc. Mensuration is about measuring 2D and 3D shapes.

Mensuration (Porimiti) Formula in Maths

With the help of formulas, you can find out and calculate different measurements. For example area, perimeter, volume, surface area, and length of different shapes. Before we learn about the mensuration formulas, let’s first understand the difference between 2D and 3D shapes. This article is important for students in school and also for those preparing for competitive exams. That have a lot of questions on mensuration. If you want to take the SSC, Bank Exams, or other government exams, you may already know that around 2-3 questions are asked in the Quantitative Aptitude section.
