there are 2 cubes what are the numbers should be there on 6 faces so i can use these as one month calender?

Question

the place of cubes can not interchange. ....and date's are 1 to 31.....for example there is a date 17th of the month then one cube's face should have number one and other one number seven.

Answer 1

You need the 10 digits 0 through 9 (obviously). You also need another 1 and 2, so you can represent 11 and 22.

Answer 2

What is a 'calender' ? Perhaps you mean a calendar !

It cannot be done without allowing the cubes to interchange. However, if you are prepared to allow them to interchange, it can be done.

One way of doing it is to have 0, 1, 2, 3, 4 and 5 on one cube and 0, 1, 2, 6, 7 and 8 on the other. The '6' would have to be turned upside-down to produce '9'. It doesn't matter much which cubes the 3, 4, 5, 6, 7 and 8 appear on. So you could, for example, have 0, 1, 2, 3, 4 and 8 on one cube and 0, 1, 2, 5, 6 and 7 on the other.

Try it and you'll find that you can generate all 31 dates.

Answer 3

The cubes must interchange to make this possible. I have one of these at home, but I come up with 13 necessary sides of the 12 available. I'll have to check it out when I get home. If they can't be interchanged, one cube would only have 3 numbers on it.

You would need one blank face, then 0 - 9 with an extra 1 and an extra 2. Unless you just used a zero for the blank for the days less than 10, then it would work, just making sure that both cubes had 1 and 2.

Answer 4

Well if the cubes were interchangable it would be easy

Cube 1 would have 1,2,6,7,8,9,
Cube 2 would have 0,1,2,3,4,5
This way you could have a full range from 1 to 31 (you would have to hide one cube during the first 9 days)

but as you say the cubes are not interchangable I am stuck, now I'm really keen to hear the answer!

Mom has answered what digits you need, but on which cube should each one be put?

Answer 5

Cube A has 1, 2, 3, 4, 5, & 6
Cube B has 0, 1, 2, 7, 8, & 9

Using these two cubes, you can make all numbers 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12,... 30, & 31.

Answer 6

To allow for a blank in place of a leading zero, use Dave's blocks, except change the 9 to a blank. For 9, 19, and 29, invert the 6.

Eh, not quite... for 7 and 8, you still need hide a cube. :(

Answer 7

0 to 10=total 10 digits.
1 and 2=total 2 digits.
Two cubes have 12 faces,each face represents 0,1,2,3,4,5,6,7,8,9,1,2 seperately so that 11 and 22 can also be accomodated.

But for adjusting digits you have to inter change.

Answer 8

I own these 2 cubes. One cube has1,2,6,7,8,0,the other is 1,2,3,4,5,0

Answer 9

Cube1 can have 0,1,2,4,5,6
Cube2 can have 1,2,3,7,8,9,

Answer 10

0,1,1,2,2,3,4,5,6,7,8,9,
