A figure with ten faces is called a decahedron. In geometry, a decahedron can refer to any three-dimensional shape that has ten flat surfaces or faces. One common example is the regular decahedron, known as a pentagonal trapezohedron, which has 10 faces that are congruent kites.
That's called a Decagon.
