Aloiza [94]

Answer:

$\sqrt{697}$

Step-by-step explanation:

If the base of the square pyramid has an area of 576 units, then the side length must have a length of $\sqrt{576}=24$ . 24/2=12, and using the pythagorean theorem you can find that the height of the pyramid is $\sqrt{29^2-12^2}=\sqrt{697}$ . Hope this helps!
