It is clear from the above, for each solid, there are three views as shown above (i), (ii), (iii) and
called them Front view (i), side view (ii), Top view (iii).
Example 4: Draw the top, front, and side views of the following solid figure made up of cubes.
Solution:
Top view Front view Side view
Think and Answer
Which of the following 3-dimensional figures has the same top, side, and front view as triangles?
Viewing Different Sections of a Solid
There are two ways to recognise different parts of a solid.
(a) by cutting or slicing (b) by casting a shadow
Viewing an Object by Cutting or Slicing
One way to view a 3D object is by cutting or slicing it to obtain its cross-section.
A cross-section is a 2D shape made by cutting or slicing any 3D object vertically or horizontally.
A cross-section is the exposed surface of a solid that you get when you make cut through it. Thus,
it does not contain any piece of the original face.
It all comes from “inside” the object.
Here is a loaf of bread. It is like a cuboid with a square face. Let us ‘slice’ it with
a knife. When you give a vertical cut, we get several pieces, as shown in the
adjoining figure. Each face of the piece is a square.
If our cut is not ‘vertical’ we may get a different cross-section.
There are a few real-life examples of viewing different cross-sections of solids:
Horizontal Cross-section Vertical Cross-section
