==== definition ====
x<sub>1</sub> is a frustum/cone/cylinder/pyramid made of material x<sub>2</sub> with larger base x<sub>3</sub> and at-most-as-large base x<sub>4</sub>, with other characteristics x<sub>5</sub>.
==== notes ====
x<sub>4</sub> cannot be larger in hyperarea than x<sub>3</sub>. A cone and a pyramid are degenerate frusta with exactly one base (x<sub>4</sub>) being exactly a point (the apex); a line segment is a doubly-degenerate frustum with x<sub>3</sub> (and therefore x<sub>4</sub>) being a point. The bases should typically be approximately parallel to one another; they need not be perpendicular to their axis. Except possibly when at least one base is a point, they will be (apprpximately) geometrically similar to one another (having the same cross-section along parallel planes wrt the axis, modulo scale/size, which will nonetheless be multiplied by a uniform factor in all 'dimensions'). A round base will produce, approximately, a circular cone or a (circular) cylinder.
