It is said that this question is not rigorous!

Except for the third floor, if the red lanterns are arranged in a rectangle according to 3×6, five can be placed in each horizontal row and two in the vertical row, which is 3 * 5+2 * 6 = 27; If you can put it between two lanterns on the diagonal, it is 27+2*5=37! Also, if a red lantern is placed at the center of the circle and other 17 lanterns are arranged in a circle around it, 17 lanterns can be placed on the circumference and 17 lanterns can be placed on the radius, and * * * meters is 17+ 17=34. I won't list the others one by one!
