Video Summary

The problem involves cutting a rectangular sheet of dimensions 192 by 84 millimeters into squares through a series of cuts. Initially, an 84 by 84 millimeter square is cut, leaving a remaining 108 by 84 millimeter rectangle. Another 84 by 84 square is then cut from this, leaving a 24 by 84 millimeter strip. This strip can be divided into three 24 by 24 squares. Finally, the leftover strip of 24 by 12 millimeters can be halved into two 12 by 12 millimeter squares. Therefore, the smallest square achievable is 12 millimeters, corresponding to option E.
