Put two toothpicks per side on one square. On the other square use one toothpick per side. You will get two squares out of twelve toothpicks.

Create a three dimensional pyramid

Old one. Make a square out of four squares, then remove two adjacent inside toothpicks. This leaves a large square with a small square inside.

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.

Start with a 2x2 square (that uses 8 toothpicks) Use the other two to make a 1x1 square in one of the corners of the big one..

This can be done in 3D. Place four toothpicks in a square shape on a flat surface. Take a further two toothpicks and place them in such a way that they for an upward triangle on two adjacent sides of the square on the floor. Take a further two toothpicks and do the sam on the other adjacent side. Take the last remaining toothpick and joint the two triangles. You have now created three equally sized squared in 3D

Try using lots of triangles and pyramids, because they are a lot sturdier and stronger than squares and pentagons and hexagons etc. But if you HAVE to use squares, then reinforce the corners by building triangles into them.

they used steel

Well you could make the structure by taking the marshmallow and shaping it into triangles and then connect it together so it looks like a bridge and then if that does not work then try building squares and then putting triangles in the middle and then getting some toothpicks to connect it. Questions Is there a limited amount of marshmallows or toothpicks you are supposed to use? Is the structure supposed to hold something? Like a text book, a book, or ect.

The straightforward answer would appear to be eight, using separate toothpicks to form each letter.(Use 3 in the F, 3 in the A, and 2 in the T.)However, if you can use the same toothpicks for all three letters at the same time, you only need three. (see related link)Using 3 ToothpicksBy overlapping the three toothpicks at the proper angles, you can simultaneously form an F, an A, and a T. Place the toothpicks atop each other to form a small triangle in the middle. You will see the letters F, A, and T within the angles formed. The horizontals of the F are, however, oddly splayed and not parallel.(see related link)

There is a pattern here: Level 1 uses 3 = 3 × 1 toothpicks Level 2 uses 6 = 3 × 2 toothpicks Level 3 uses 9 = 3 × 3 toothpicks So it looks like each level uses 3 times the level number of toothpicks. ı→ 3 × level = 24 → level = 24 ÷ 3 = 8 So Level 8 uses 24 toothpicks.

The sides were congruent with each other.

use styrofoam balls and use toothpicks

as toothpicks? They use the spikes to defend themselves against predators.

N0- you can't use one square.

Flat colored toothpicks are good! I don't know why the colored is better, it just is! The flat are also good. If you can't find flat colored toothpicks go with flat probably, or use both!

Depends on what type of box you're using!

This is a popular riddle that should be illustrated for explanation.(see the related link and question)The answers are :It takes 8 if you don't break any, or bend any, and use separate toothpicks to form each letter. (There are 3 in the F, 3 in the A, and 2 in the T.)Only 1 if you break it into pieces. You can also bend it into four equal lengths, then cross the lengths into a star shape as below.Only 3 if you can use the same toothpicks for all three letters. By overlapping the three toothpicks at the proper angles, you can simultaneously form an F, an A, and a T. Place the toothpicks atop each other to form a small triangle in the middle. You will see the letters F, A, and T within the angles formed. The horizontals of the F are, however, oddly splayed and not parallel.It depends on how big you want to make it.
