SSC Mensuration notes: 500 Questions Series advance math PDF

Significance of this chapter:

• 5-6 questions come from this chapter in tier 1 and 10-12 questions in tier 2.
• So extremely important chapter, also part of ADVANCE MATH ( Mensuration, Geometry, Trigonometry, Algebra)
• Formulae/identities/properties are extremely important for this chapter and should be on your tips.

Concepts and Key Points

• 2 – D : Under two dimensions we will study
  • Triangle
  • Quadrilateral
  • Polygons
  • Circle
• 3 –D : Under three dimensions we will study
  • Cube
  • Cuboids
  • Box
  • Cylinder
  • Prism
  • Cone
  • Pyramid
  • Frustum
  • Sphere
  • Hemisphere
  • Tetrahedral

Important: For 2 D area and perimeter are calculated and for 3 D volume and surface area are calculated.
