What is unknown?
Which nets can be used to make cube.
This question is based on the concept of \(3D\) shapes
Figure (ii), (iii), (iv) and (vi) will make cubes. As we know a cube has \(6\) faces, \(12\) edges and \( 8\) vertices. So, when we will fold the nets of shapes in (ii), (iii), (iv) and (vii) we will be able to make a cube.
