It will be roughly 67.08 inches.
We can solve this using the Pythagorean Theorem, which is listed below.
![a^{2} + b^{2} = c^{2}](https://tex.z-dn.net/?f=%20a%5E%7B2%7D%20%2B%20%20b%5E%7B2%7D%20%3D%20%20c%5E%7B2%7D%20)
In this equation, we use a and b as legs of a triangle and c is the hypotenuse. We can treat the length and height of the bookcase as legs and use this equation to solve for the diagonal (also known as the hypotenuse)
![30^{2} + 60^{2} = c^{2}](https://tex.z-dn.net/?f=%2030%5E%7B2%7D%20%2B%2060%5E%7B2%7D%20%3D%20c%5E%7B2%7D%20)
![900 + 3600 = c^{2}](https://tex.z-dn.net/?f=%20900%20%2B%203600%20%3D%20c%5E%7B2%7D%20)
![4500 = c^{2}](https://tex.z-dn.net/?f=%204500%20%3D%20c%5E%7B2%7D%20)
67.08 = c
The temperature went down by 10 degrees F. An exothermic reaction happened because the temperature went down so heat was released.
