Both are prisms. A prism is a 3D shape which has a uniform cross section, so anywhere along it's length where you take a slice you always see the same shape. To say which prism you mean we add the name of this cross section 'triangular prism', 'hexagonal prism' etc. We have a special name for a circular prism - a cylinder. Also, a rectangular prism is a cuboid.
It is the height of the prism. There is no need for another name!
