VIEW OF 3-D SHAPES
A 3-D object can look differently from different positions so it can be drawn from different perspectives.

Example 1. Let there be a combination of three cubes, one on the top of the other as shown in the adjoining figure. What will be its top and side view?
NCERT Solutions(Part- 1)- Visualising Solid Shapes Class 8 Notes | EduRev
Solution:
(i) If we look at this solid structure from the top, we would see just a square.  NCERT Solutions(Part- 1)- Visualising Solid Shapes Class 8 Notes | EduRev
(ii) If we look at it from a side, i.e. left or right, then we would see a figure as shown here. NCERT Solutions(Part- 1)- Visualising Solid Shapes Class 8 Notes | EduRev
Note: In this case the front view would also be the same.

Example 2. Look at the combination of four cubes as shown in the adjoining figure. Show its various views.
