To solve the problem of identifying each solid figure in the image, we need to recognize and classify each 3D shape based on its geometric properties. Below is the solution with explanations for each figure:
---
1)
-
Shape: A pyramid with a triangular base.
-
Type: Triangular Pyramid (or Tetrahedron).
---
2)
-
Shape: A polyhedron with pentagonal bases and rectangular lateral faces.
-
Type: Pentagonal Prism.
---
3)
-
Shape: A cube, which is a regular hexahedron with six square faces.
-
Type: Cube.
---
4)
-
Shape: A pyramid with a square base.
-
Type: Square Pyramid.
---
5)
-
Shape: A pyramid with a triangular base.
-
Type: Triangular Pyramid (or Tetrahedron).
---
6)
-
Shape: A polyhedron with a pentagonal base and triangular lateral faces.
-
Type: Pentagonal Pyramid.
---
7)
-
Shape: A perfectly round 3D object.
-
Type: Sphere.
---
8)
-
Shape: A pyramid with a hexagonal base.
-
Type: Hexagonal Pyramid.
---
9)
-
Shape: A cone with a circular base.
-
Type: Cone.
---
10)
-
Shape: A cylinder with circular bases.
-
Type: Cylinder.
---
11)
-
Shape: A polyhedron with rectangular bases and rectangular lateral faces.
-
Type: Rectangular Prism (or Cuboid).
---
12)
-
Shape: A polyhedron with hexagonal bases and rectangular lateral faces.
-
Type: Hexagonal Prism.
---
Final Answer:
\[
\boxed{
\begin{array}{ccc}
1) & \text{Triangular Pyramid} & 2) & \text{Pentagonal Prism} & 3) & \text{Cube} \\
4) & \text{Square Pyramid} & 5) & \text{Triangular Pyramid} & 6) & \text{Pentagonal Pyramid} \\
7) & \text{Sphere} & 8) & \text{Hexagonal Pyramid} & 9) & \text{Cone} \\
10) & \text{Cylinder} & 11) & \text{Rectangular Prism} & 12) & \text{Hexagonal Prism} \\
\end{array}
}
\]
Each figure has been identified based on its geometric characteristics, such as the shape of its base and the nature of its faces.
