2. A cube is made up of six congruent square faces. Find the length of the inner diagonal of the cube. Note that is the hypotenuse of right triangle ADH. (Round your answer to the nearest hundredth.)
a) Use the 45-45-90 property or the Pythagorean Theorem to find the length of the diagonal (DH) of the bottom base of the cube.
b) Use the length from part a as one leg, the length of side AD, and the Pythagorean Theorem to find the length of the diagonal AH.
