Summary

So far in this chapter, we have studied the following points:

  • Surface area of a cuboid = 2(lb+bh+hl) sq.units
     
  • Surface area of a cube = 6a2 sq.units
     
  • Curved surface area of a cylinder = 2prh sq.units
     
  • Total surface area of a cylinder = 2pr(r+h) sq.units
     
  • Curved surface area of a cone = prl sq.units
     
  • Total Surface area of a right circular cone = pr(l+r) sq.units
     
  • Surface area of a sphere of radius r = 4 pr2 sq.units
     
  • Curved surface area of a Hemisphere = 2
  • pr2 sq.units
    • Total surface area of a Hemisphere = 3 pr2 sq.units
       
    • Volume of a cuboid = l ´  b ´  h cu.units
       
    • Volume of a cube = a3 cu.units
       
    • Volume of a cylinder = pr2h cu.units
       
    • Volume of a cone = pr2h cu. units
       
    • Volume of a sphere of radius r = pr 3 cu.units
       
    • Volume of a hemisphere = pr 3cu.units
