Well, since it is a cube, we know the length of all the sides of 10 cm, so we can create a triangle using the sides of a square and use pythagorean theorem
A²+B²=C²
C being the hypotenuse, or the diagonal we are looking for, so 10²+10² = 200
Then we square root to find C, so √200 = 14.14213562

First do 3x3, which is 6.
Then do 1/2 x 1/2. Convert the 1/2's to .50's
Do .50 x .50. Start with 5 x 5, and get 25. Then move decimal 2 places over.
Now that you have 6 and .25, add them and get 6.25.
.25 as a fraction is, of course, 1/4
Your final answer should be 6 1/4
