Name of the Solid

What is the name of the solid formed by cutting a pyramid or a cone by two parallel lines? 


Answer:  Frustrum: The technical translation of ‘Frustrum’ would be a’ piece broken off’

However it can be used to refer to that portion of a regular solid left after cutting off the upper part by a plane parallel to the base. It can also be used to describe the portion intercepted between any two planes.
