A square has 4 sides therefore 3 squares from 12 toothpicks will simply be three unconnected squares
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.
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.

6 SQUARES arranged in a 3-dimensional form , make a CUBE .
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?
A cube is a 3-dimensional figure whose six faces are all squares.
1. circles 2. triangles 3. squares 4. any of the polygons
A triangular prism.
A cube has six faces and all are congruent squares.
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!

3 squares: 36 + 4 + 1 2 squares: 25 + 16
A square has 4 sides therefore 3 squares from 12 toothpicks will simply be three unconnected squares
