1.
For the given foundation plan, select the orthographic drawing set.

 a. Set 2 b. Set 4 c. Set 3 d. Set 1

#### Solution:

An orthographic drawing shows the top view, front view and right-side view of a three-dimensional figure.

The following three-dimensional figure can be developed from the given foundation plan.

The top view, front view and right-side view of the given object are as shown.

Set 3 represent the orthographic views of the three-dimensional figure.

2.
Find the number of cubes required to make the structure.

 a. 15 b. 16 c. 17 d. 14

#### Solution:

Count the number of cubes in the structure.

The number of cubes required to make the structure are 16.

3.
Select the incorrect statement.
 a. An isometric drawing shows the corner view. b. An isometric drawing is used to represent two dimensional drawing only. c. An orthographic drawing shows a top view, front view and right-side view. d. A foundation diagram shows the base of a structure and the height of each part.

#### Solution:

An isometric drawing is a type of three-dimensional drawing.

It shows three sides of an object in a single drawing.

An isometric drawing of a three-dimensional object shows a corner view of the figure.

So the statement, 'An isometric drawing is used to represent two-dimensional drawing only' is the incorrect statement.

4.
What type of view does the following figure represent?

 a. Isometric view b. Right-side view c. Top view d. Front view

#### Solution:

The given figure is three-dimensional.

An isometric drawing is a pictorial diagram that shows three faces of an object in one view.

An isometric drawing shows a corner view. So, it is an isometric view.

5.
For the given foundation plan, select the isometric drawing.

 a. Figure 2 b. Figure 1 c. Figure 4 d. Figure 3

#### Solution:

An isometric drawing is a pictorial diagram that shows three faces of an object in one view.

The following three-dimensional figure can be developed from the given foundation plan.

Figure 3 represents the isometric drawing for the given foundation plan.

6.
Select the foundation diagram for the isometric drawing.

 a. Figure 2 b. Figure 3 c. Figure 4 d. Figure 1

#### Solution:

An isometric drawing shows a corner view of a three-dimensional figure.

A foundation drawing shows the base of the structure and the height of each part.

Count the number of blocks the isometric drawing has in each row on its base.

Figure 1 gives the foundation drawing of the three-dimensional figure.

7.
Recognize the foundation plan for the given stucture.

 a. Figure 3 b. Figure 4 c. Figure 2 d. Figure 1

#### Solution:

The given structure is a three-dimensional figure.

A foundation drawing shows the base of the structure and the height of each part.

Count the number of blocks the isometric drawing has in each row on its base.

Figure 3 gives the foundation drawing of the three-dimensional figure.

8.
What type of view does the cake represent?

 a. Left-side view b. Top view c. Front view d. Right-side view

#### Solution:

An orthographic drawing shows a top view, front view and right side view.

Only the top of the cake has been shown in the picture.

So, it is a top view.

9.
Identify the structure that is constructed using 5 cubes.

 a. Figure 1 b. Figure 3 c. Figure 2 d. Figure 4

#### Solution:

Count the number of cubes in each structure.

Figure 2 is a structure constructed using 5 cubes.

Figure 3 is a structure constructed using 9 cubes.

Figure 1 is a structure constructed using 6 cubes.

Figure 4 is a structure constructed using 8 cubes.

Hence Figure 2 is the answer.

10.
Recognize the view for the given isometric figure.

 a. Front view b. Right side view c. Left side view d. Top view

#### Solution:

The given figure is three-dimensional.

An orthographic drawing shows a top view, front view and right-side view.

The view that is shown in the figure is the front view.
