• 3D Shapes from Nets – Example
• What’s Next?

In the previous segment, we learnt how to convert a net to its solid. In this segment, we will look at a few nets and find out if they can form 3D shapes.

Example

Q. There are four nets whose faces are squares as shown below:

1

2

Nets

Which of the above nets when folded will result in a cube? Solution:

Net 1:

Net 1

Place the net as if it is lying on the plane. Make the bottom two squares vertical. The shape will look like as follows:

Step 1

Make the squares on either side vertical as follows:

Step 2

From this shape, no matter how it is folded, a cube cannot be formed.

Net 2:

Net 2

Drawing the net as if it is lying on a plane as follows:

Step 1

Make the faces on the top and bottom vertical as shown below:

Step 2

Tilt the two square faces on the left on their adjacent square. Also, raise the square at the extreme right vertical to get the following figure:

Step 3

Tilt the three faces on the right to the left. This gives a cube.
