Problem Statement

How many square inches of paint are needed to fully paint a regular 66-sided die with side length 22 inches, except for the 13\frac13-inch diameter circular dots marking 11 through 66 (a different number per side)? The paint has negligible thickness, and the circular dots are non-overlapping.
