According to dimensions, there are two types of shapes:
1.Two-dimensional shapes (2-D shapes)
2.Three-dimensional shapes (3-D shapes)
We have learned about 2-D shapes. Now let’s learn about 3-D shapes.
- 3-D means ‘Three-dimensional’.
- 3-D shapes or Three-dimensional shapes are solid figure or objector shape that has three dimensions – length, width, height.
- 3-D shapes have thickness.
- 2-D shapes are flat when drawing it on paper.
- 3-D shapes are fat not flat. 3-D shapes have thickness.
- To classify 3-D shapes we look edges, corners, faces/sides of the shapes.
There are various3-D shapes. Let’s learn about it.
- A sphere is a perfectly round solid shape. It has no sides, no corners. It has one curved face that goes all around.
- A cube is a solid shape with 6 square faces and 8 corners.
- A cuboid is a solid shape with 6 rectangular faces and 8 corners.
- Some pair of faces (not all) of a cuboid can be square.
A cone is a solid shape that has a circular bottom and it all goes around up to one point.
