A decahedron.
It is important to learn and remember the name of 3D shapes. A 19 faced 3d shape is called a nonadecahedron.
It is called a Triacontakaidigon.

well. it is called icosahedron
That 3D shape is called triangular pyramid.
It is called a Triacontakaidigon.
CUBOID
A tetrahedron, also called a pyramid is a three-dimensional shape with four faces.
A three-dimensional figure with 30 faces is called a triacontahedron.
You can have a 3d shape with any no of sides 3d only means there are three measure needed to calculate volume, or in other words you can pick it up and touch it. These three measurements are width, depth and height. If the faces all had to be of the same area and flat there might not be a 7 sided 3d shape (or a regular one at least) there can always be a n-sided non-irregular shape even a 1,253,703-sided irregular shape is theoretically possible.
