The students lined up in a three story hollow phalanx, with a total of 72 people, and there were peo

Let the outermost layer have x people on each side and the innermost layer has x 2-(y-1) 2=72, (x+y-1)*(x-y+1)=72, considering x and y are positive integers and parity, there are three sets of equations that can be solved, 72=36*2=18*4=12*6, respectively.

The first group of x+y-1=36, x-y+1=2, the solution is x=19, y=18, the second group is x+y-1=18, x-y+1=4, the solution is x=11, y=8, and the third group is x+y-1=12, x-y+1=6, and the solution is x=9, y=4.

There are three groups of joint solutions, 19 people in the outermost layer, 18 people in the innermost layer, 19*19-17*17=72, 11 people in the outermost layer, 8 people in the innermost layer, 11*11-7*7=72, 9 people in the outermost layer, 4 people in the innermost layer, 9*9-3*3=72.

Lined up in a hollow phalanx male 72 people 3 layers, each layer 72 3 = 24 people 12 people in the outermost layer, 8 people in the middle layer, and 4 people in the innermost layer. There are 2 people on each side of the innermost level.

5 pcs. Subtract four corners from each layer to get 4 sides, a total of 12 people, set the innermost layer after subtracting x people on each side, then you can get 60 = 4 [x+(x+1)+(x+2)], solve x=4, because of subtracting the people on the corners, then the innermost layer has 5 people on each side.

According to the inscription column, it is calculated as follows: the innermost layer has:

16 people.

16 people in the innermost layer and 24 people in the second floor. 48 people on the third floor.

This is a problem arranged in a three-layer square, with a total of 72 and 72 3.

This is a very simple question, and if the answer should be 70, it would be true.

The students lined up in a two-layer hollow square, with 10 people on each side of the outer layer, and there were 68 people in this square.

If there are 10 people on each side of the outer layer, then the number of people on each side of the inner layer should be 10-1=9, and because it is a phalanx, the number of people in the outer layer is 10*4-4=36(The horizontal and vertical rows of the phalanx will overlap, and there are a total of 4 more people in the four corners, so the total number of people is minus 4 people) The number of people in the inner layer is 9*4-4=32, so there are a total of 36+32=68 people.

The outermost layer has 10 people on each side, and the square has 4 sides.

The number of people in the outer layer is 10 * 4-4 = 36 people (The 4 minus is 4 people in the four corners, which is the number of people weighing 4102 complexes.) or (165310-1)*4=36 people).

Because the rule of the hollow square is that the difference between the total number of people in each layer is 8 (the difference in the number of people on each side is 2, and the difference in the number of people on 4 sides is 8), then the number of people in the inner layer is 36-8 = 28 or (10-2) * 4-4 = 28 people The total number of people in the square is 36 + 28 = 64 people.

Solution: The number of people in the outer layer: (10-1) x4 = 36 people.

Number of people on the inner floor: (10-2-1) x4 = 28 people.

Total number of people: 36 + 28 = 64 people.

It is the large solid square (side length is 10) minus the small solid square (side length is 6).

A three-layer hollow phalanx of students, and the outermost layer of 56 people is known, so there are 138 students in total.

The outermost layer has 14+1=15 people on each side, then the middle layer has 15-2=13 people on each side, this layer has a total of (13-1) 4=48 people, and the innermost layer has 13-2=11 people on each side.

There are (11-1) 4=40 students on this level, so there are 56 + 48 + 40 = 144 students in this team.

A: There are 144 students in this team.

If it is an equal number of phalanxes, then there are x in the first layer, 2x in the second layer, and 3x in the third layer, then x = 12, so there are 36 in the last layer, then the head and tail of Anbian are counted, and Lu Xun on each side has 10.

Hollow phalanx, with a difference of 8 people on two adjacent floors.

The middle floor has: 120 3 = 40 people.

The outermost layer has a total of 40 + 8 = 48 people.

On each side: 48 4+1=13 people.

Summary. Hello, there are 352 students in the school, lined up in a four-layer hollow square, we assume that the outermost layer has x people on each side, so there are 4x-4 people in the outermost layer. The second floor has x-2 people on each side, so the second layer has 4(x-2)-4=4x-8 people.

The third level has x-4 people on each side, and the third layer has 4 (x-4)-4=4x-20 people. The fourth floor has x-6 people on each side, and the fourth floor has 4 (x-6)-4=4x-28 people. So 4x-4+4x-8+4x-20+4x-28=352,16x=448,x=28

There are 352 students in the school, lined up in a four-layer hollow square, and how many people are on each side of the outermost layer of this square.

This is a complicated question.

Hello, there are 352 students in the school, lined up in a four-layer hollow square, and I assume that there are x people on each side of the outermost layer, so there are 4x-4 people in the outermost layer. The second floor has x-2 people on each side, so the second layer has 4(x-2)-4=4x-8 people. The third floor has x-4 people on each side, and the third floor has 4 (x-4)-4=4x-20 people.

The fourth floor has x-6 people on each side, and the fourth floor has 4 (x-6)-4=4x-28 people. So 4x-4+4x-8+4x-20+4x-28=352,16x=448,x=28

So there are 28 people on each side of the outermost layer.

If you don't understand something, feel free to ask.

There are no unknowns, and that's it.

Good. The doll hasn't learned yet.

Good. There are 8 more people in the outermost row, 16 more than the third row, and 24 more than the fourth row. That is to say, 1st row + 4th row = 2nd row + 3rd row.

352 2 = 176, 176 2 = 88, the average number of people in the first and fourth rows is 88, the first row is 24 more than the fourth row, 88 + 24 2 = 88 + 12 = 100 people. So there are 100 people in the first row (the outside of the most leaky vertical side), (100+4) 4=26 people.

There were 26 people in the outermost row.

Sorry, there was an error in the value of the first method.

The correct answer is 26 people.

Thanks a lot. If you have any questions, feel free to ask me questions. Good.

Summary. There are 88 people, the specific explanation is as follows:

No matter how many people there are on each side, there are 8 more people on the outside than in the middle, and in the middle than on the inside (four corners + four repetitions, just draw your own picture). So 240 3 = 80 gives 80 people in the middle layer, plus 8. The outer layer is 88 people.

240 people are lined up in a three-tier hollow phalanx, so how many people are on each side of the outer layer.

Hello. Hello.

There are 88 people on the edge, and the specific explanation is as follows: no matter how many people there are on each side, there are 8 more people on the outside than in the middle, and there are 8 more people in the middle than in the inside (four corners + four repetitions, and the funny Jane will understand it by drawing it by himself). So 240 3 = 80 gives 80 people in the middle layer, plus 8.

The outer layer is 88 people. Mountain pants.

Q: Each edge? Each side 4 is 22 people.

Isn't it 21 2 = 23.

No, it's 80 4 20 people per floor, and then there are 8 more people per floor 4 2, then 20 + 2 = 22 people.

30 (name), A: There are 30 students on each side of the outermost base layer of the square formation

So the answer is: 30

Summary. Dear, hello, there are 192 people in the third grade arranged in a four-layer hollow phalanx, and how many people are on each side of the innermost layerAnswer: If there are x people on each side of the innermost layer, then there are (x+2) people on each side of the second layer, (x+4) people on each side of the third layer, and (x+6) people on each side of the fourth layer.

According to the title, the total number of people in the four-layer hollow square matrix is 192 people, and the equation can be listed: 4 (x-1) + 4 (x+2-1) + 4 (x+4-1) + 4 (x+6-1) = 1924 (x 1) + 4 (x + 2 1) + 4 (x + 4 1) + 4 (x + 6 1) = 192 So, there are 10 people on each side of the innermost layer.

Dear, hello, there are 192 people in the third grade arranged in a four-layer hollow phalanx, and the innermost layer of the innermost layer of Sakura Hong is the answer of how many people on each side: If there are x people on each side of the innermost layer, then there are (x+2) people on each side of the second layer, (x+4) people on each side of the third layer, and (x+6) people on each side of the fourth layer. According to the inscription, the total number of hollow phalanxes in the four early layers is 192 people, and the equation can be listed:

4 (x-1) + 4 (x+2-1) + 4 (x+4-1) + 4 (x+6-1) = 1924 (x 1) + 4 (x + 2 1) + 4 (x + 4 1) + 4 (x + 6 1) = 192 So, there are 10 people on each side of the innermost layer.

Pro, the second solution answer: for the Xunyan Bridge in the hollow phalanx, the outermost number of people on each side of the jujube = total number of people 4 layers + the number of layers per mu of the outermost layer of the number of people on each side is: 192 4 4 + 4 = 16 (people) four layers of hollow phalanx, the outermost layer and the innermost layer are 4-1 = 3 (layers), and each layer is 2 people on each side.

The number of people on each side of the innermost layer is: 16-(4-1)*2=16-6=10 (people) Answer: 10 people on each side of the innermost layer.

Middle phalanx: 120 3 = 40 (people).

Outermost phalanx: 40 + 2x4 = 48 (people).

Each side: 48 4 + 1 = 13 (people).

A: There are 13 people on each side.
