There are many possible answers:
Some examples:
a sphere truncated by two planes not intersecting within the sphere,
an ellipsoid similarly truncated,
a torus (doughnut) with a segment removed,
a cylinder.
the flat surfaces of a solid figure are the
A SPHERE has no vertices and no FLAT surfaces
The flat surface of a solid figure is called a face. For example, a rectangular prism has 6 flat surfaces and therefore 6 faces.
A cube

A sphere.
What figure has 6 flat surfaces that all look exactly the same
A SPHERE has no vertices and no FLAT surfaces
The flat surface of a solid figure is called a face. For example, a rectangular prism has 6 flat surfaces and therefore 6 faces.

pentagon
A face is the flat surface on a solid figure. For example, a triangular prism has five flat surfaces and therefore five faces.
