Streszczenie
Let $E$ be a (IV)-polyhedral Banach space. We show that, for each $\epsilon \gt 0$, $E$ admits an $\epsilon $-equivalent (V)-polyhedral norm such that the corresponding closed unit ball is the closed convex hull of its extreme points. In particular, every separable isomorphically polyhedral Banach space has this property.
