1, first fold the middle of the colored paper into a cross, and then fold the four sides into a crease.
2. Turn to the back and fold three corners inward. Then fold the three corners in the crease direction, and then fold the edges inward. 3. Turn the colored paper to the back and fold the two corners on the left inward.
4. Fold the right middle part upward. Turn the colored paper upside down, fold the corners inward, and do the same folding at each corner.
5. Continue to rotate and then fold. After folding, insert two pieces of origami together.
Extended data:
A cuboid is a right prism with a rectangular bottom. A cube is a special kind of cuboid. A cube is a cuboid with six sides all square.
Each rectangle of a cuboid is called the face of the cuboid, the line where the face intersects the face is called the edge of the cuboid, and the point where the three sides intersect is called the vertex of the cuboid. The sum of the six areas of a cuboid is called the surface area of a cuboid. The volume of a cuboid is the unit of measurement of a cuboid, which is equal to the product of its length, width and height.
trait
(1) A cuboid has six faces. The reverse sides of each group are exactly the same.
(2) A cuboid has 12 sides, and four opposite sides are equal in length. According to the length, it can be divided into three groups, each group has four sides.
(3) A cuboid has eight vertices. Each vertex connects three edges. The three edges of a cuboid are called length, width and height.
(4) Two adjacent sides of a cuboid are perpendicular to each other.
A cube is a three-dimensional figure surrounded by six identical squares. A straight parallelepiped with square sides and bottom is called a cube, that is, a hexahedron with equal sides, also known as a cube and a regular hexahedron.
Cubes are special cuboids. Dynamic definition of cube: a three-dimensional figure obtained by translating the side length of a square in the direction perpendicular to the plane of the square.

A cube has eight vertices, and each vertex is connected by three edges.
[2] A cube has 12 sides, and each side has the same length.
(3) A cube has six faces, and each face has the same area.
