7 squares is forty nine so you remove two toothpicks to make the digits 49
2 rectangles. Put two toothpicks on 2 sides and one on the other side, and that uses 6 toothpicks and if you make another rectangle like that you make 2 rectangles.
the answer is 12 :)
12
3 squares and 4 triangles will have 24 vertices. There will be 4 vertices for each of the 3 squares. Since there are 3 squares, that will be 12 vertices. There are 3 vertices for each of the 4 triangles. Since there are 4 triangles, that will be 12 vertices. 12+12=24.
Fuor toothpicks from 16 leave 12 which, by coincidence (?) is exactly enough for four equilateral triangles!
A square has 4 sides therefore 3 squares from 12 toothpicks will simply be three unconnected squares
You can arrange them into a cube to make the 6 faces of the cube, and the 12 toothpicks making up the 12 edges of the cube.
bend 2 toothpicks at 90 degree angles and put them cornor to cornor
The 12 toothpicks were arranged into the letters N-I-N-E-I, with toothpicks forming an N (3), I (1), N (3), E, (4) and I (1). She throws away the one that makes the last I, so she is left with N-I-N-E. (the letters now spelled out by the remaining eleven 11 toothpicks)

You make 3-D! Look... 6 squares in one cube and you can do that with toothpicks too!

1o triangles
There are 12 triangles in 2 hexigons
You can arrange them to make a cube.12 edges, 6 faces.
