How many of the following can be made into a cube ?

 

A cube is a three-dimensional shape having 6 square faces, 8 vertices and 12 edges. All the faces of a cube is in square shape.

So, we need exactly 6 square faces to make a complete cube.

Now, counting the number of faces in each of the given figures, we get :-

shape A : 6 square faces

shape B : 6 square faces 

shape C : 5 square and 1 triangle faces

shape D : 6 square faces

Hence, the correct option will be option C because the number of shapes that can be folded into a cube is $3$ i.e. shape A, shape B and shape C.
