# Three Dimensional Worksheets

What is the Difference Between Two and Three-Dimensional Shapes? A two dimensional shapes refer to the shapes that have only length and height as its dimensions. Because two-dimensional shape lie on a flat surface, they are also known as plane figures or plane shapes. While they have an area, two-dimensional shapes have no volume. It is plotted in a graph on the x- and y- axes. Examples: The Triangle, The Square, The Circle, The Rectangle. Whereas a three dimensional shape has length, height, and width (depth) as its dimensions. It is plotted in a graph on the x-, y- and z- axes. Examples: Dice - Cube, Shoe Box - Cuboid or Rectangular Prism, Globe - Sphere, Soda Can - Cylinder.

• ### Basic Lesson
