Question

Identify the nets which can be used to makes cubes.(cut out copies of the nets and try it)

Answer 1

Hint: On folding the net if we get the cube then we consider it as a net to make cubes. Check all the options and see what all options can make a cube.

Complete step-by-step answer:
(i) The given net can be folded as follows:

When the faces that are in the sky blue colour and in pink colour are folded to make a cube, they will be overlapping each other.
So net (i) cannot be used to make a cube.
Let us consider the net (ii)
(ii) The given net can be folded as follows:

A cube can thus be formed in the above way.
So we can say that net (ii) can be used to make a cube.
Let us consider the net (iii)
(iii) The given net can be folded as follows:

A cube can thus be formed in the above way of folding.
So we can say that net (iii) can be used to make a cube.
Let us consider the net (iv)
(iv) The given net can be folded as follows:

A cube can thus be formed in the above way.
So we can say that net (iv) can be used to make a cube.
Let us consider the net (v)
(v) The given net can be folded as follows:

When the faces that are in the blue color and in red color are folded to make a cube, they will be overlapping each other.
So net (v) cannot be used to make a cube.
Let us consider the net (vi)
(vi) The given net can be folded as follows:

A cube can thus be formed in the above way.
So we can say that net (vi) can be used to make a cube.

Net (i), (ii), (iii), (iv), (vi) can be used to form a cube.

Note: A skeleton outline of a solid that can be folded to make the solid is called a net of that solid. A particular solid can have many types of nets.
