cube There are a great many solid shapes that have only flat surfaces.
A solid shape that can slide is a cube. Its flat surfaces allow it to easily slide along a surface.
A cone
A 2 dimensional shape such as a circle is NOT a solid shape, while a sphere is.
A solid figure with 2 flat surfaces and 0 vertices is a cylinder. A cylinder has two circular flat surfaces, known as bases, and no vertices because it does not have any corners or points where edges meet. It is a three-dimensional shape that is formed by a curved surface connecting the two bases.
