Three-dimensional Shapes


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.

1. Sphere:

  • A sphere is a perfectly round solid shape. It has no sides, no corners. It has one curved face that goes all around.
