It looks like you've uploaded an image showing various
3D shapes with their names labeled. Here's a breakdown of the 3D shapes shown in the image and a brief explanation of each:
---
🔷 1. Cuboid
-
Description: A three-dimensional shape with six rectangular faces, where opposite faces are equal.
-
Properties:
- 6 faces (all rectangles)
- 12 edges
- 8 vertices
-
Example: A brick or a box.
---
🔷 2. Sphere
-
Description: A perfectly round 3D shape where every point on its surface is equidistant from the center.
-
Properties:
- No edges or vertices
- One continuous curved surface
-
Example: A ball.
---
🔷 3. Cylinder
-
Description: A shape with two parallel circular bases connected by a curved surface.
-
Properties:
- 2 circular faces (top and bottom)
- 1 curved surface
- No vertices
-
Example: A can or a pipe.
---
🔷 4. Triangular Prism
-
Description: A prism with triangular bases and three rectangular sides.
-
Properties:
- 5 faces (2 triangles + 3 rectangles)
- 9 edges
- 6 vertices
-
Example: A tent or a wedge-shaped block.
---
🔷 5. Cone
-
Description: A 3D shape with a circular base and a single vertex (apex) at the top.
-
Properties:
- 1 circular base
- 1 curved surface
- 1 vertex
-
Example: An ice cream cone.
---
🔷 6. Pentagonal Prism
-
Description: A prism with two pentagonal bases and five rectangular lateral faces.
-
Properties:
- 7 faces (2 pentagons + 5 rectangles)
- 15 edges
- 10 vertices
-
Example: A building with a pentagon-shaped base.
