Cutting Squares I:

#1	Divide the squares of 10x10, 11x11 and 12x12 in the least quantity of pieces, that reordering the pieces you can form a 13x13 and 14x14 square. Example: Here is with only 10 different pieces:

Cutting Squares II:

#2	If allow that you use copies of only one shape, the solution would be using 365 squares of 1x1. But what is the least quantity of pieces needed if only 2 shapes are allowed?

Cutting Squares III:

#3	As 2) but you can use only 3 different shapes. Example: Here is a solution with 39 diferent pieces: I used 33 , 4 and 2 , so 33 + 4 + 2 = 39 pieces.

Cutting Squares IV:

#4	As 2) but you can use only 4 different shapes

Cutting Squares V:

#5	As 2) but you can use only 5 different shapes.

Send me the 5 solutions. The one who uses the least quantity of pieces will be the winner.
