How many dimensions does a solid have?

Hint: To find the dimensions of any figure, one can check in how many directions or planes can that figure be drawn. Any figure can be either 1-dimensional, 2-dimensional or 3-dimensional.

Complete step-by-step answer:
When we consider a line, we can see that it can be extended in only one direction. It has a length but no thickness, so it is 1-dimensional.
When we consider a square or a rectangle, it is known that these figures can be drawn in more than one direction. They have a length as well as breadth and can be drawn on a plane. Hence, they are 2-dimensional.
When we consider solid objects in real life, we can see that they have length, breadth and height as well. They project out of the plane of paper. So, these objects are 3-dimensional. Some examples are cube, cuboid, cylinder etc.

Note: For 1-D objects, check if they have a length. For 2-D, check if they have both length and breadth. For 3-D objects, check if they have all the three dimensions-length, breadth and height.
