Description

"Project Study Designing and Making a Packaging Box with a Cuboid Shape" Preliminary PPT of Geometric Figures

Part One: Knowledge Objectives

By making a rectangular-shaped packaging carton, you can further understand the unfolded diagram of a quadrangular prism, and initially learn to comprehensively use mathematical knowledge and methods to solve simple practical problems.

Design and make a rectangular-shaped packaging carton PPT, part two: target breakthrough

Target: Expanded view of three-dimensional figures

Example 1 Textbook Supplementary Example Questions Among the four figures in Figure 4-4-1, each small square is marked with a color. If the colors on two opposite sides of a cube are required to be the same, then the following cannot be the expansion diagram of the cube: ()

Example 2 Supplementary Examples to the Textbook Please follow the steps below to make a square prism.

Step 1: As shown in Figure 4-4-2(1), fold a square piece of paper in half to make 16 small squares of the same size;

Step 2: As shown in Figure 4-4-2(2), cut out the shaded part in the picture;

Step 3: As shown in Figure 4-4-2(3), fold the piece of paper along the crease and glue it with tape.

Design and make a rectangular-shaped packaging carton PPT, the third part: summary and reflection

Knowledge points: Design and make rectangular-shaped packaging cartons

1. Steps to design a rectangular box:

When designing a cuboid packaging box, you must first draw an expanded diagram of the cuboid, then cut it out and fold it into a rectangular parallelepiped.

2. The design of the graphics and text on the box must be novel, meaningful, and beautiful.

As shown in Figure 4-4-3, it is an expanded view of a cuboid box without a lid (overlapping parts are not counted). Find the volume of the box.

Solution: The length of a cuboid box without a lid is 5, the width is 3, and the height is 1, so the volume of the box is 5×3×1=15.

Is the above solution correct? If it is incorrect, please explain the reason and correct it.

Solution: Incorrect, because I couldn’t imagine the geometry, I got the length, width, and height of the cuboid wrong.

Correct answer: As can be seen from the figure, the length of the cuboid box without a lid is 3, the width is 2, and the height is 1, so the volume of the box is 3×2×1=6.
