1) What is the minimum number of squares that would be sufficient to create each of the following patterns?

2) Twenty-seven identical cubes are placed together to form the object below. If one of the cubes is displaced, four different shapes are possible: one in which the missing cube is at the corner of the stack, one where it is in the middle of an edge of the stack, one in which it is in the middle of a side of the stack, and one in which it is at the core of the stack. If two of the small cubes are removed rather than one, how many different shapes are possible?
