6\sqrt2

Why?

We have the isosceles right triangle. The length of legs are 6. Use the Pythagorean theorem:

h^2=6^2+6^2\\\\h^2=36+36\\\\h^2=36\cdot2\to h=\sqrt{36\cdot2}\\\\h=\sqrt{36}\cdot\sqrt2\\\\h=6\sqrt2

In general, the formula for calculating the hypotenuse in an isosceles right triangle is h=a\sqrt2

a - a leg, h - a hypotenuse
