The moving sofa problem, which deals with the math of how shapes can fit around corners, may have been solved by a Korean mathematician. UC Davis mathematician Dan Romik has made a study of the ...

Learn more A simple semi-circular sofa shape would need the width of at least one unit, and as the semi circle would have a radius of one also, the formula would be: π over two, which = 1.57.
