2. What are 3D Shapes? 3D shapes are solid shapes or objects that have three dimensions (which are length, width, and height), as opposed to two-dimensional objects which have only a length and a width. Other important terms associated with 3D  geometric shape are faces, edges, and vertices. They have depth and so they occupy some volume. Some 3D shapes have their bases or cross-sections as 2D shapes. For example, a cube has all its faces in the shape of a square. Let us now learn about each 3-dimensional shape (3D shape) in detail. 3D shapes are classified into several categories. Some of them have curved surfaces; some are in the shape of pyramids or prisms.

3. Real-Life Examples of 3D Geometric Shapes In mathematics, we study 3-dimensional objects in the concept of solids and try to apply them in real life. Some real-life examples of 3D shapes are shown here which are a soccer ball, a cube, a bucket, and a book.

4. What is the net of a 3D shape? The net of a 3D shape is what it looks like if it is opened out flat. A net can be folded up to make a 3D shape. There may be several possible nets for one 3D shape. You can draw a net on paper, then fold it into the shape.

5. Types of 3D Shapes ! There are many 3 dimensional shapes (3D shapes) that have different bases, volumes, and surface areas. Let us discuss each one of them. Cube Cuboid Cylinder Cone Square Based Pyramid Triangular Based Pyramid Prism

6. Net Of Cube❗ A cube has 11 nets. They can all seen here. Number of Edges – 12 Number Of Vertices - 8 Number of Faces - 6

7. Net Of Cuboid❗ A Cuboid has 54 different nets. A couple of them are shown here. Number of Edges – 12 Number Of Vertices - 8 Number of Faces - 6

8. Net Of Cylinder❗ The two nets shown here both form cylinders. Number of Edges – 2 Number Of Vertices – 0 Number of Faces - 3 (1 curved surface and 2 circular faces)

9. Net Of Cone❗ Number of Edges – 1 Number Of Vertices – 1 Number of Faces - 2

10. Net Of Square Based Pyramid❗ Number of Edges – 8 Number Of Vertices – 5 Number of Faces - 5 Remember that in a Square Based Pyramid , all triangles are equal in size.

11. Net Of Triangular Based Pyramid❗ Number of Edges – 6 Number Of Vertices – 4 Number of Faces - 4 Remember that in a Square Based Pyramid , all triangles are equal in size.

12. Net Of Prism❗ Number of Edges – 6 Number Of Vertices – 9 Number of Faces - 5 This is the net of a triangular based prism. Prisms can have any shape for the base. All prisms are made up of two of the base shapes along with rectangles. The number of rectangles is equal to the number of sides the base shape has.

13. Can You Draw The Net Of A Pentagonal Prism ❓ The Answer Is Shown On The Next Slide………

14. A Pentagonal Prism has 2 Pentagons. Since a pentagon has 5 sides, them the net will also consist of 5 rectangles. This is a Pentagonal Prism
