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

Kind of hard to draw on here, but first you make a plus sign using 4 toothpicks, then you make a box using the remaining 8 around the plus sign: ___ ___ | | | ___ ___ | | | ___ ___

Fuor toothpicks from 16 leave 12 which, by coincidence (?) is exactly enough for four equilateral triangles!

# Make a plus sign with 4 toothpicks. # Make a large square around the plus sign with the remaining toothpicks (2 toothpicks per side) You now have 4 small squares inside 1 large square... total of 5 squares.

make a circle

Yes. Make one triangle using hree matches. Underneath the two vertices at the base of this triangle, make another two triangles, using six more matches. You will find that there is an inverted triangle in the middle - the fourth.

Make a two by two grid with six toothpicks, and then place the other two toothpicks at a 45 degree angle on the corner of two of the squares.

Area of triangle = 1/2 base times height1/2 * 12 * 4 = 24

Area of triangle: 0.5*12*4 = 24 square inches

A rhombus.

using four of them you make a square then using the remaining two make a criss cross in the middle of the square.

No because a trapezoid has 4 sides and a triangle has three if a trapezoid had three then it would be a triangle. If you had 3 trapezoids you could make a triangle!

Area of the triangle: 0.5*6*4 = 12 square inches

The perimeter of the equilateral triangle is 3 times 4 = 12 cm

You arrange 12 toothpicks into a large square, subdivided into four squares : 2 toothpicks on each side and four more, one each from the middle of the sides to the center of the large square. Now you have four (small) squares. Take away 2 adjacent toothpicks from the ones in the center, and you have 2 squares : one remaining small one and the large one that has the small one inside it. (see related link)

The area of triangle is : 12.0

Are these numbers decimals? Is it 14.35 inches and 3.15 inches? If that is the case, then 14.35/3.15 = 4.56 or 4 toothpicks.

Four equilateral triangles make up another equilateral triangle.

no

assuming by boxes you mean squares in two dimensions its easy. Make the five boxes all next to each other so they share sides then remove two toothpicks here the top and bottom of a middle box and you are left with 4.
