Example 1

easy
Classify each object by its dimension: a point, a line, a square, a cube.

Solution

  1. 1
    Step 1: A point has no length, width, or depth β€” it is 0-dimensional.
  2. 2
    Step 2: A line extends in one direction (length) β€” it is 1-dimensional.
  3. 3
    Step 3: A square has length and width β€” it is 2-dimensional.
  4. 4
    Step 4: A cube has length, width, and height β€” it is 3-dimensional.

Answer

Point: 0D, Line: 1D, Square: 2D, Cube: 3D.
Dimension counts the number of independent directions you can move within an object. Each time we add a perpendicular direction, we increase the dimension by 1.

About Dimension

The number of independent directions needed to specify any location in a given space or object. A point is 0D, a line is 1D, a plane is 2D, and space is 3D. Dimension determines which measurement formulas apply and how quantities scale.
