Visualizing Solid Objects

solid may also depend upon the direction or side from where it is seen. Moreover, in combined shapes
some part of the solid may be hidden from the view.

Let’s take some cubes and arrange them as shown in the figure.
Can you guess how many cubes are required to make this structure.

A little thinking will give you the answer. Yes, it is 7. One can look at this
combination from the front, side or the top. Each time we get a different view.
The three views are shown in the following grid paper. Front Side
