A polyhedron
A sphere.
That's a Sphere not Cylinder cuz it had flat Circles Above and
Prism
One whose boundaries are straight lines.
The face of a triangle is the flat surface of the solid figure. _________________________________________________ A face is a side of a 3 dimensional figure. So, the number of faces a triangle would be 0.
a polyhedron
A solid figure that has flat faces that are polygons is called a polyhedron. Polyhedra have various forms, such as cubes, tetrahedra, and octahedra, each defined by the shape and number of their polygonal faces. The faces of a polyhedron are connected by edges, and the points where the edges meet are called vertices. Examples include regular polyhedra, where all faces are identical polygons, such as the Platonic solids.
cube
a sphere
A cube is a solid figure called a polyhedron. A polyhedron is a solid figure with all flat faces. So a cone would be a solid figure but not a polyhedron becasue it has a curve and does not have all flat faces.
The flat surface of a solid figure is called a face. For example, a rectangular prism has 6 flat surfaces and therefore 6 faces.
In mathematics, a face is a flat surface that is a constituent of a three-dimensional geometric object, such as a polyhedron or a solid. Faces are typically polygons, such as triangles, rectangles, or pentagons, and they help define the shape and structure of the object. For example, a cube has six faces, each being a square.
A face is the flat surface on a solid figure. For example, a triangular prism has five flat surfaces and therefore five faces.
A square is not a solid figure at all. It's a flat figure, with four congruent faces and four congruent angles.
A sphere.
How about a sphere
Soda can or cylinder
