  2. Rectangle and cube are both 2-dimensional.

  3. Rectangle is 2-dimensional and cube is 3-dimensional.

  4. None of these

Show answer
Correct Option: C
Explanation:

The difference in rectangle and cube is that a rectangle is a 2-dimensional figure where the length and the breadth of the geometry are specified.

 A cube is a 3-dimensional figure where the length, breadth and depth of the geometry are specified.
