Full form of 3D is "Three Dimension". Three dimension geometric shapes are the figures which has length, breadth and height.
 
Examples of 3D geometric shapes: -
 
  • Sphere
  • Cylinder
  • Cone
  • Cuboid
  • Cube

 
3D Shape Definition Examples Formula
Sphere The solid generated by revolving a circular alumina about any of its diameters, is called the sphere. Football, volleyball, etc.,
  • Volume = 4/3 πr^3
  • Surface area = 4π r^2
Cylinder The solid bounded by a circular curved surface and two identical bases. Circular pillars, circular pipes, circular pencils, measuring jars, road rollers and gas cylinder etc.,
  • Volume = π r^2 h
  • Curved surface area= 2 π r h
  • Total surface area= 2πr(r + h)
Cone The solid generated by the rotation of a right- angled triangle about one of the sides containing the right angle is called a right circular cone. Ice-cream cone, conical vessel, clown’s cap, etc.
  • Volume= (1/3)π r^2 h
  • Curved surface area= πr√( h^2 + r^2) = π r l
  • Total surface area= π r (l + r)
Cuboid A solid bounded by six rectangular faces is called a cuboid. Matchbox, chalk box, brick, tile, book, etc.,
  • Volume= l * b * h
  • Diagonal=√(l^2+b^2+h^2 )
  • Total surface area =2(lb+bh+lh)
  • Lateral surface area =2 ( l + b) * h
Cube A cuboid whose length, breadth and heights are all equal is called a cube. Dice, ice cubes, sugar cubes etc.,
  • Volume= a^3
  • Diagonal = √3 a
  • Total surface area= 6 a^2
  • Lateral surface area= 4 a^2
