# make the shapes of cubes, cylinders and cones using nets

Able to make the shapes of cubes, cylinders and cones using nets especially designed for this purpose.

Able to make the shapes of cubes, cylinders and cones using nets especially designed for this purpose.

Nets of cuboid: Open out a match box and layout on the white paper. Draw the base sides of the match box.

Teacher: Do you see, “How many sides are there in a match box?”

Student: yes sir. There are 6 sides.

Teacher: You are right. Can you assemble/create it after dissemble?

Student: Yes sir.

Teacher: Good

The net is a two dimensional shape and it always forms three-dimensional shape.

A net is a two dimensional figure which can be folded to form a three dimensional figure.

Try these

Find out which of these can be made into a box by folding along the dotted lines. Put a tick mark for the correct option. Net of a cube: Fold squares along the dotted lines. Hence six equal squares from the net of a cube.

Net of a cylinder: Consider a rectangle and two equal circles. This net thus formed is a cylinder.

Join the two edges of a rectangle breadth wise in such a way that the length of the rectangle forms the boundary of one circle at the top and other circle at the bottom.

The length of the rectangle forms the boundary of the circle. Both of them are equal in length.

Net of a cone: Look at the figure.

Join both the portion of a circle in such way that the arc of the circle falls on the boundary of the circle attached at the bottom.

The length of the arc forms the boundary of the circle. Both of them are equal in length

Activity

Match the net with the shape you will get by folding. Tags : Geometry | Term 1 Chapter 1 | 5th Maths , 5th Maths : Term 1 Unit 1 : Geometry
