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
• 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.
