The answer is Miors. To find out key one you just have out find what the opposite sides of dice which add to 8, add to e.g. (6+1+1=8 )(1+6+6=13). THEREFORE the first key number is 13.The order for the second key number is 8+5+4+7+9 therefore the second key number is 9.To find out the third key number ,the formula to use is length(9cm) minus (radius(2.5cm)+radius(2.5cm)= 4cm. Square it and subtract 1= 15 which is your answer. For the fourth problem the corners are 2+9+6+1=18 which is your answer. The answer for the fifth key is 19 because if you subtract 3 from 19 you get 16 which is divisible by 4 and is you subtract 1 you get 18 which is divisible by 3.For the last question the key numbers are 13=M 9=I 15=o 18=r 19=s So the answer is Miors.
