Here is an incomplete net for making a cube. Complete it in at least two different ways. Remember that a cube has six faces. How many are there in the net here?
(Give two separate diagrams. If you like, you may use a squared sheet for easy manipulation.)
Solution:
A cube is a 3-D solid object with six square faces and all the sides of a cube are of the same length.
The net of a cube is formed when the 3D figure with the square faces is flattened by separating at the edges making it into a 2D figure. Through the net of the cube, we can clearly see the six faces.
There are 3 faces in the net given here.
The given cube net with 6 faces can be completed in the following ways.
Three faces of the cube have been given so, we can implement the other three faces in this way to get a completed cube. The dotted lines show the inclusion of 3 new faces as drawn below.
