This table lists the volumes of the Platonic solids [1] given that either the edge length $a$ equals $1$, the inner radius $r$ equals $1$, the midradius $\rho$ equals $1$, the outer radius $R$ equals $1$, or the surface area $A$ equals $1$.
How they were obtained: Computed in interval or ball arithmetic throughout, so the digits written follow from the width of the result rather than from a guard chosen in advance.
