PPT on understanding cuboids, part 2: exploring new knowledge

Knowledge points The names of the parts of cuboids and cubes

(1) Which objects in life are shaped like cuboids or cubes?

Knowledge refining

In a cuboid or cube, the flat part of the surface is called a face, the edge where two faces intersect is called an edge, and the three edges intersect at one point, which is called a vertex.

Knowledge points Characteristics of cuboids and cubes (key points)

(2) What are the characteristics of cuboid and cube? Do it, fill it out, and talk to your peers.

Knowledge points: The relationship between cuboid and cube (difficult point)

(3) Is a square a special rectangle and a cube a special rectangular parallelepiped? Recognize it and think about it.

Knowledge refining

A cube can be thought of as a special rectangular parallelepiped with equal length, width, and height.

PPT on the understanding of cuboids, part three: consolidation exercises

1. The picture on the right is a rectangular box. (The upper and lower sides are approximately the same, unit: cm) (Selected from textbook P12 T2)

⑴What shape is the top of this box? What are the length and width? Which face has the same shape and size as it? What about the left side?

Answer: The top of this box is rectangular, with a length of 36cm and a width of 28cm. The bottom of the box is the same shape and size. The left side is a rectangle with a length of 28cm and a width of 10cm. The right side has the same shape and size.

(2) Which side is 36cm long and 10cm wide?

Answer: The length of the front and back of the box is 36cm and the width is 10cm.

2. The cuboids below are all made of small cubes with an edge length of 1cm. What are their length, width and height? (Selected from textbook P12 T3)

3. True or false questions.

(1) A cube has 6 faces, each face is a square. ( )

(2) A cuboid has 12 edges and 8 faces. ( )

(3) A three-dimensional figure with 6 faces, 8 vertices and 12 edges must be a cuboid. ( )

(4) If two faces of a cuboid are square, then the areas of the remaining four faces of the cuboid are equal. ( )

(5) The characteristics of the cuboid are also possessed by the cube, so the cuboid is a special cube. ( )

PPT on understanding cuboids, part 4: Class summary

What knowledge have you learned in this class?

Each of the six faces of the cuboid is a rectangle (in special cases, two opposite faces are squares); the three edges that intersect at the same vertex are called the length, width, and height of the cuboid.

The 6 faces of the cube are identical squares; the 12 edges are all equal in length.

A cube can be thought of as a special rectangular parallelepiped with equal length, width, and height.
