Mensuration Formulas Now let’s learn all the important mensuration formulas involving 2D and 3D shapes. Using this mensuration formula list, it will be easy to solve the mensuration problems. Students can also download the mensuration formulas list PDF from the link given above. In general, the most common formulas in mensuration involve surface area and volumes of 2D and 3D figures. Mensuration Formulas for 8 class Mensuration Formulas for 9 class Mensuration Formulas for 10 class Mensuration Formulas for 11 clas Mensuration Formulas for12 class Mensuration Formula in Maths 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. Before moving on to the mensuration formulas, let us first understand the difference between 2D and 3D figures. 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. 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. These Mensuration formulas are also important for Class 8, 9 10 students, so stay tuned and allow us to help you master your exams. Mensuration Formulas for 2-D Figures The area of 2-D figures is always calculated in square units and the perimeter is always calculated in units. 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. Have a look at these mensuration formulas, understand them and learn them by heart. Mensuration Formulas for 2-Dimensional Figures Shape Area, Perimeter Circle πr² ,2 π r Square (side)²,4 × side Rectangle length × breadth,2 (length + breadth) Scalene Triangle √[s(s−a)(s−b)(s−c), Where, s = (a+b+c)/2 a+b+c (sum of sides) Isosceles Triangle ½ × base × height ,2a + b (sum of sides) Equilateral Triangle (√3/4) × (side)² ,3 × side Right Angled Triangle ½ × base × hypotenuse A + B + hypotenuse, where the hypotenuse is √A²+B² Parallelogram base × height 2(l+b) Rhombus ½ × diagonal1 × diagonal2 4 × side Trapezium ½ h(sum of parallel sides) a+b+c+d (sum of all sides) Mensuration Formulas for 3-D Figures Under 3-D Figures, we can calculate the total surface area which is equal to curved surface area+ area of top and bottom. Curved surface area is also known as lateral surface area, and is measured in square units. Total surface area is also measured in square units whereas volume is measured in cubic units. So, find out the mensuration formulas for 3-D figures such as cone, cylinder, cube, cuboid, sphere, etc. Mensuration Formulas for 3-Dimensional Figures Shape Area Curved Surface Area (CSA)/ Lateral Surface Area (LSA) Total Surface Area (TSA) Cone (1/3) π r² h π r l πr (r + l) Cube (side)³ 4 (side)² 6 (side)² Cuboid length × breadth × height 2 height (length + breadth) 2 (lb +bh +hl) Cylinder π r² h 2π r h 2πrh + 2πr² Hemisphere (2/3) π r³ 2 π r² 3 π r² Sphere 4/3πr³ 4πr² 4πr²
