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.
You can make 5 triangles out of 9 toothpicks. With 6 toothpicks, make a large triangle with 2 toothpicks for each side. Now, take individual toothpicks, and make a smaller triangle inside the larger one by joining the midpoints of the sides of the previous triangle. (The vertices of the smaller triangle are the midpoints of the sides of the larger one).
Because a triangular pyramid has 6 edges
24 toothpicks.
5 or 6 Depending on what shape you are thinking of
You can arrange them to make a cube.12 edges, 6 faces.
Use them to form the edges of a cube.

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.
Take two toothpicks that create an outside corner. Cross them like a + inside one of the remaining boxes. Count the new four smaller boxes inside it as 4, the one they are formed in as 5, and the two untouched boxes as 6 and 7. (The trick is to remember to count the larger box the 4 are formed in.)
Since every square has 4 sides and you only have 10 toothpicks, obviously you can't have the squares be separate. You will need exactly 2 toothpicks to overlap. Once you realize that, there are two shapes that are possible and can be rotated to make a total of 6 different solutions. A straight line (vertical or horizontal): = = = | | | | = = = Or an L-shape (forwards, backwards, and upside-down forwards and backwards): = | | = = | | | = = Sorry that these don't look quite right, the formatting is getting screwed up.

make a hexagon(six-sided shape)
24 toothpicks.
6 triangles is 18 and 3 squares is 12 18 +12 ------- 30
Polygons with 4, 6, 8, 10, 12, 14 or 16 sides.
