Exercise 1 Page 840

We are asked to describe how to use isometric dot paper to sketch the following figure, which is a right rectangular prism that is 5* 6* 4 units.

Let's look at isometric dot paper.

It allows us to draw three-dimensional figures on a two-dimensional paper easily by connecting dots. A 1* 1* 1 cube can be represented as below.

Now, let's follow the steps below for sketching the given prism.

1. Mark a corner of the solid.
2. Draw 4 units down from the corner.
3. Draw 5 units left from the corner.
4. Draw 6 units right from the corner.
5. Draw two other sides of a rectangle in the top base of the prism.
6. Draw segments 4 units down from the left and the right vertex for the vertical edges.
7. Connect the appropriate vertices to make bottom sides.
8. Draw additional lines that represent meshes on the three faces.
9. Add some colors and shadings if desired. We will!
