3) Use two other wooden blocks to represent 1-31 days.
2. Make a calendar of events.
1. Group cooperation.
2. Teachers provide guidance.
3. Exhibition and exchange.

Make a calendar with four cubes:
1. The first cube is used to write the month, 1-12 months, write two months on each side, and turn each other upside down.
2. The second cube is used to write the ten digits of the date, a maximum of 31 days in a month, therefore, this cube only needs to write 0-3, with four sides, each side has a number.
3. The third cube is used to write the single digit of the date. This cube needs to write the ten numbers 0-9, 0 and 8 each use a face separately, because the two of them are the same when they are reversed, 9 occupies a single face, and it can be made as "6" when it is reversed. The remaining 123457 have three remaining faces, and two numbers are written on each side, reversed.
4. The fourth cube is used to write the week, because there are seven days in a week, and the cube has only six sides, so one face is written from Monday to Friday, and Saturday and Sunday are reversed and written on the same side.
5. Finally, find a box, put the four small cubes together, line them up, and you're done with an event calendar.

First, put the four cubes flat on a plane to form a shape of a hand square, and then randomly remove the cube on a corner and put it on top of the cube opposite it, and stack it neatly.

A wooden block has 6 faces, and each side shows two months, which can show 12 months.
The specific writing is: the first side of the wooden block represents January and February; The second side of the block represents March and April; The third side of the block represents May and June; The fourth side of the block represents July and August; The fifth side of the block represents September and October; The sixth side of the block represents November and December.
A cube has 6 faces, and a year has 12 months, so one face should represent 2 months.

Cut 12 small pieces vertically, make a small hole at the top of each small piece, and circle it in turn with a round iron ring, which is simple and easy to operate. Thank you.

Draw a diagonal line on every six sides, so that you can write twelve months.

According to the analysis of the stem, this figure has only 1 layer and 2 lines, so there are 3 different ways to build it;
So the answer is: 3

10=1*10=2*5
There are 2 ways to build (if you count 2 horizontal and vertical combinations of the same shape, there are 4 types).
Surface area of 1*10: 1*1*2+1*10*4=2+24=26 (square centimeters).
The number of small cubes in a large cube is determined by the fractions of the sides of the large cube for example, if it is divided into 2, there will be 8 small cubes, and if it is divided into 3, there will be 27 small cubes. The general formula divides the sides into n parts, and you get n times n and then n small cubes. i.e. n at the same time, the total number of points is subtracted by 1 >>>More
One more language, one more hope.
If the Earth is a cube and is stable in the universe, there is something wrong with the laws of physics. The breaking of rotational symmetry means that the conservation of angular momentum no longer exists, Kepler's second law no longer holds, and our common concept of "moment" in the principle of leverage will also be problematic, because the rotational symmetry of space has been broken, so the position of the lever must be determined in order to be studied. >>>More
The first method: take a container, put in the potatoes, add water, measure the volume, then take out the potatoes and measure the volume again. Take the volume you just measured and subtract the volume you have measured now, which is the volume of the potato The second method is to use its density * its weight = volume.
When I first saw the original manga, it was recommended by a friend. I was particularly curious at the time, a stickman comic, what's there to see? Later, I tried to chase it, but I couldn't stop. >>>More
