### What is the total number of possible outcomes in the calendar?

• A.

14

• B.

13

• C.

12

• D.

11

D. 11
Explanation
The total number of possible outcomes in the calendar refers to the number of different ways the days of the week can be arranged. In a standard calendar, there are 7 days of the week. However, since the starting day of the week can vary, there are only 7 distinct arrangements. Additionally, there are 4 different possibilities for the number of weeks in a month (4, 5, 6, or 7 weeks), resulting in a total of 7 x 4 = 28 possible outcomes. However, since there are only 12 months in a year, the total number of possible outcomes is limited to 12. Therefore, the correct answer is 12.

### How many characters make up the set of letters often used in the calendar?

• A.

12 characters

• B.

18 characters

• C.

28 characters

• D.

10 characters

B. 18 characters
Explanation
The set of letters often used in the calendar includes the 12 letters representing the months (January to December) and the 6 letters representing the days of the week (Sunday to Saturday). Therefore, the total number of characters in this set is 12 + 6 = 18 characters.

### In the set of cubes, what does 6 double as?

• A.

18

• B.

12

• C.

9

• D.

7

C. 9
Explanation
In the set of cubes, the number 6 doubles as 9. This means that if you were to multiply 6 by 2, the result would be 9.

• 4.

### How many faces of the cubes have numbers 3, 4, 5 on them?

• A.

4 faces

• B.

9 faces

• C.

7 faces

• D.

3 faces

D. 3 faces
Explanation
A cube has 6 faces in total. Since the numbers 3, 4, and 5 are mentioned on the faces, it is clear that these three faces have those numbers. Therefore, the correct answer is 3 faces.

### When was the problem of two-cube calendar first discussed in a publication?

• A.

1995

• B.

1994

• C.

1993

• D.

1992

### On how many faces is the solution to the two-cube calendar established?

• A.

31 faces

• B.

30 faces

• C.

3 faces

• D.

7 faces

A. 31 faces
Explanation
The solution to the two-cube calendar is established on 31 faces. This means that when the two cubes are arranged in a calendar format, there are a total of 31 visible faces. Each cube has 6 faces, so when they are combined, there are 12 faces that are not visible. Therefore, the solution is established on the remaining 31 visible faces.

Rate this question:

• 7.

### Which day of the month does the front faces of the two cubes indicate?

23rd day

• B.

15th day

• C.

20th day

• D.

25th day

D. 25th day
Explanation
The front faces of the two cubes indicate the 25th day of the month.
