1, because the total * * * has four layers, the outermost layer is 12, and the innermost layer is 6, so there should be two layers in the middle, one layer is 10, and the other layer is 8, so that the total can be calculated, because it is a square with four sides,12.

2. Number of people on the outermost floor: 60/4= 15. By analogy, one side of each floor is 13, 1 1, 9, 7, 5, 3, 1.

Total population: 60+13 * 4+1* 4+9 * 4+7 * 4+5 * 4+3 * 4+1* 4 = 256.

3. If there are 46 telephone poles to be divided into 45 sections, then the length of this road is: 12*45=540 (m) 540\20+ 1=28 (root).

4. Not sure, it should be 2 1 root.
