Nets of 3D shapes

Nets of 3D Shapes for Class 5 Maths

Nets of 3d shapes show us the opened-out flat diagram of geometrical shapes. Here students will learn about nets of solid shapes.

In this learning concept, the students will also learn to

• Classify cube nets, nets of cuboids.
• Identify nets cylinder and nets of the cone.
• Evaluate the cube net diagram, cuboid net diagram, cylinder net diagram, and net diagram of the cone.

Each concept is explained to class 5 maths students using illustrations, examples, and mind maps. Students can assess their learning by solving the two printable worksheets given at the page’s end.

Download the class 5 maths nets of 3d shapes worksheet and check the solutions to the nets of 3d shapes question for class 5 provided in PDF format.

             

 Nets of Solid Shapes:

• A three-dimensional shape can be made by folding 2D shapes.
• When a three-dimensional solid is unfolded a two-dimensional shape is obtained.
• Those 2D solids which are used to make a 3D shape are called .

           

  Cube Nets:

• A cube has 6 faces.
• Each face of the cube is a square. Therefore, when a cube is unfolded it will give 6 squares.
  
• There are 11 nets of a cube.
• The figure of each net is shown below.
  

  Not every net which has 6 square faces can be folded into a cube.

  Examples:

  

             

Nets of Cuboid:

• A cuboid has 6 faces.
• Each face of the cuboid is a rectangle. Therefore, when a cuboid is unfolded it will give 6 rectangles.
  
• There are 54 different nets of the cuboid.
• Few nets of the cuboid are shown below.
  

  Not every net which has 6 rectangular faces can be folded into a cuboid.

  Examples:

  

               

 Net of Cylinder

• A cylinder has 3 faces.
• Two of the faces are circular and one is rectangular.
• Therefore, when a cylinder is unfolded it will give 2 circles and 1 rectangle.
  

  The figure given below cannot be folded into a cylinder.

  

             

 Net of Cone

• A cone has 2 faces.
• One curved face and one flat face.
• A net of cones has two parts:
• One is the circle which represents the flat part.
• The second one is the sector which represents the curved part.
• Therefore, when a cone is unfolded it will give one circle and one sector.

The net given below cannot be folded to a cone.
