"Understanding of Cuboids" Cuboid PPT Courseware

Talk about it

In life, what other objects have you seen that are shaped like a cuboid or a cube?

What are the characteristics of cuboids and cubes? Please find it and fill it in the form below.

fill in the blank

A cuboid has ( ) faces. Each face is ( ), and there may be two opposite faces ( ). The opposite face ( ) is a cuboid with ( ) edges, and the opposite edge length is ( ). The cuboid has ( ) vertices.

A cube is a three-dimensional figure surrounded by ( ) identical ( ). There are also ( ) edges, and their lengths are ( ). The cube has ( ) vertices. Since the sides of a cube are all equal in length, its length, width, and height are all called ( ).

Fill in the blanks orally based on the data in the figure:

Figure 1: The length of the cuboid is ( ) centimeters, the width ( ) centimeters, and the height ( ) centimeters. The sum of the lengths of the 12 edges is ( ) centimeters.

Figure 2: A cuboid whose length, width, and height are 9 cm, 3 cm, and 2.5 cm respectively. The length on it is ( ) centimeters, the width is ( ) centimeters, the length of the left side is ( ) centimeters, and the width is ( ) centimeters. The sum of the lengths of the three edges that intersect at a vertex is ( ) centimeters.

Give it a try:

Measure the length, width, and height of the math book, and then talk about the length and width of each side.

What is the shape of this chalk box? What is its edge length? How many faces are exactly the same?

imagine

1. What is the area of ​​the left side of the cuboid in square centimeters?

2. Which surface has an area of ​​36 square centimeters?

Summary of this lesson:

Through the study of this lesson, we have a basic understanding of cuboids and cubes, and know the basic characteristics of cuboids and cubes. In life, we often see cuboids. If we pay attention to our lives, we will learn a lot of mathematical knowledge.
