You can make three squares
So whats the question? If i had 5 squares remove 3 lines to make 4 squares but keep the 3 lines within the 4 squares what?
3 squares: 36 + 4 + 1 2 squares: 25 + 16
You make 3-D! Look... 6 squares in one cube and you can do that with toothpicks too!
Is this question supposed to have 12 toothpicks to make 4 squares and then move 3 toothpicks to make 3 equal sized squares? Answer depends on the restrictions. Just move 3 sticks from any square to form a straight vertical or horizontal line up of squares is one option if there is no restrictions other than the three resulting squares are equal sizes.

First lay out 13 sticks to make 3 squares with a sick over. Then take 1 stick out. What is left is 3 squares. Simple!
move
A square has 4 sides therefore 3 squares from 12 toothpicks will simply be three unconnected squares
8 with 3 left over
Use squares and try it out for yourself. Get a number of squares and make a rectangle 3 squares long by 4 squares wide. Count the squares. You should have 12 squares (or 3*4). That's the best way I know to prove the formula.
A cube.

12 toothpics making 4 squares would be: ._ _ |_|_| |_|_| Turning this into 3 squares requires 3 tooth pics to be moved to make (ignore the dots, they're just to line things up!) ._ ...._ |_|_|_| ...|_|
Move 3 lines "from" - do you mean 'remove 3 lines from' - or - move 3 lines to other places? Anyway, this all depends on the layout of the five squares.
