We want to expand the toppings while keeping them non-overlapping, and possibly add some blank pieces of the same \"certain kind\", such that the entire cake is covered. How many blanks must we add?\n  We study this question in several cases: (1) The cake and toppings are general polygons. (2) The cake and toppings are convex figures. (3) The cake and toppings are axes-parallel rectangles. (4) The cake is an axes-parallel rectilinear polygon and the toppings are axes-parallel rectangles.
