1. Prepare materials:
Knife, glue, wooden stick (a little thinner, straight).
2. Method: Use the wooden stick to cut it into 12 sections, of which 8 sections are longer and equal in length; The other 4 paragraphs are slightly shorter and of equal length;
Glue the long 8 segments to form two squares.
Paste one of the other 4 segments to the four vertices of the square, and the other 4 endpoints to the four vertices of the other square.
1. Quadrangular prism.
A prism with both the upper and lower bottom surfaces square, and the side edges perpendicular to the bottom surface, is called a quadrangular prism. A tetraprism is a special case of parallelepiped. To put it simply, regular quadrangular prisms are further a special case of cuboids.
Let the length of the bottom edge be a and the length of the side edge be h, then its volume can be expressed as v=a*a*h.

Here's how:1. First of all, fold the length or width of a piece of paper into three rectangles, and the length of the width of the three rectangles conforms to any two that is greater than the third.
2. Then you can enclose the three rectangles into a triangular prism.
In geometry, a triangular prism is a type of cylinder with a triangular base. A regular triangular prism is a type of semi-regular polyhedra and uniform polyhedron. A triangular prism is a pentahedral body with a set of parallel faces, i.e., two faces parallel to each other, while the normals of the other three surfaces are on the same plane (not necessarily parallel faces).
These three faces can be parallelograms. All cross-sections parallel to the base are identical triangles.
Because the triangular prism can also be regarded as a trihedron with 2 vertices truncated, it is also called a truncated trihedron, and because the regular triangular prism has symmetry and is composed of 2 kinds of regular polygons, some people call the regular triangular prism a semi-regular pentahedron.
Generally, a triangular prism has 5 faces, 9 edges, and 6 vertices.

How to practice prisms: first determine the width and height of the six sides of the hexagonal prism connected together, and draw the first face, a rectangle. The details are as follows:
Then, according to the set height and width, draw the other 5 faces, making a total of 6 faces; Select a face and attach it to its top face, a hexagonal shape with the same side length and the width of the rectangle.
Then draw a hexagonal shape that looks exactly like the top surface, use it as the bottom surface, and place it underneath.
Finally, the drawings are cut out of the paper and stitched together, and a hexagonal prism is completed.
A prism is a common three-dimensional polyhedron in geometry, which refers to a closed geometry in which the upper and lower surfaces are parallel and congruent, and the side edges are parallel and equal. If the base surface of a prism is n-sided, then the prism is called an n-prism. For example, a triangular prism is a prism with a triangular base.
Prisms are the simplest of polyhedra, and some common objects, such as prisms, bricks, and bolt heads, are in the shape of prisms. A prism is formed by the overall translation of a plane made of straight lines along a straight line that is not parallel to this plane.
The polyhedron enclosed by two faces of a prism parallel to each other, the rest of the faces are quadrilateral, and the common edges of each of the two adjacent quadrilaterals are parallel to each other, and the polyhedron enclosed by these faces is called a prism. Prisms are represented by letters that represent the vertices of the base.

First, draw 5 rectangles in a row on the paper, such as 10 cm long and 4 cm wide, the length and length are connected; Then draw a regular pentagon with a width of 4 cm on the top side of the pentagon. Each interior angle is 72 degrees; Then do the same under the rectangle, drawing an identical regular pentagonal shape on one side of a pentagonal shape as wide; Finally, all the outer contours are cut out to form a pentagonal prism. As shown in the figure below:

In geometry, a triangular prism is a cylinder with a triangular bottom surface.
01 The square paper is folded out of the "ten" trace, and the upper and lower sides are folded to the center line.
02 The left and right sides are also folded to the midline, open the first two steps, and fold the 4 corners as shown in the following figure.
03 Fold the top and bottom sides to the midline, turn to the other side, and fold the left and right sides to the midline.
04 Stuff one corner into the gap, and the other corner into the gap, and the prism is ready.

A triangular prism is a pentahedral and has a set of parallel faces, i.e., two faces parallel to each other, while the normals of the other three surfaces are on the same flat surface (not necessarily parallel faces).
These three faces can be paralleloquadruple Navu sides. All cross-sections parallel to the base are identical triangles.
Because the triangular prism can also be regarded as a trihedron with 2 vertices truncated, it is also called a truncated trihedron, and because the regular triangular prism has symmetry and is composed of 2 kinds of regular polygons, some people call the regular triangular prism a semi-regular pentahedron because of the Cryptosoogen.
Generally, a triangular prism has 5 faces, 9 edges, and 6 vertices.

Materials: a pair of scissors, a pair of scotch tape for early resale, and a discarded box.
1. Prepare discarded pill boxes or other paper packaging boxes.
2. Prepare a pair of scissors, how can you do manual work without scissors?
3. Prepare a transparent glue, this wide version of transparent glue is firm, easy to use, and is a necessary item for manual work.
4. Open all the cartons and lay them on the table.
5. From the diagram, the longitudinal total is divided into quarters, and the triangular prism we need to do is enough to need thirds, so from the left, cut off the first division.
6. After cutting, it is like this.
8. Put two equal parts together, and simply glue them with transparent glue first (first simple glue, and then we have to glue them again as a whole after we finish it).
9. Stand up the carton model, the purpose of this is to know the shape of the small triangle at the bottom.
10. Use scissors to cut off the excess part. In this way, the small triangle at the bottom is cut out, and the other end is also cut out in this way.
11. In this way, the small triangles at both ends are cut.
12. Fold one of the small triangles in half to make it look like the one in the picture.
13. Glue the small triangle firmly with transparent glue.
14. The small triangular base at the other end is also treated in the same way.
15. After the two small triangles are firmly glued, gently press the world with your hand to better fix it.
16. Goodbye, all the other parts that are not sticky are glued again.
17. After sticking it, gently press it all with Lu You's hand to make the surface of the real triangular prism smoother.
18. The paper triangular prism model is done.
At most, you can cut out a heptagon, which intersects five of the edges and intersects the base, exactly seven intersections. >>>More

1.Four cans of milk powder that children have drunk, wrapped in cloth or paper and glued together, with a small plywood on top, can be used as a small table for play, and the cans can also contain some of their toys. Note that after the lid of the can is pressed on the plastic box board with a peg, the nail head should be disposed of, the nail head should be knocked flat with a hammer, and then glued with hot melt glue so that the child will not be pricked. >>>More
