- To find the longest pole that can fit in the hall, calculate the hall's diagonal using the 3D Pythagorean theorem.

- The formula for the 3D diagonal is $\sqrt{(l e n g t h^{2} + w i d t h^{2} + h e i g h t^{2})}$ .

- For this hall, it calculates to $\sqrt{(60^{2} + 30^{2} + 20^{2})}$ .

- This simplifies to $\sqrt{(3600 + 900 + 400)} = \sqrt{4900}$ .

- The square root of 4900 is 70.

- Therefore, the longest pole that can fit in the hall is 70 feet.

- Option 1: 70 feet is correct.

- Option 2: 20 feet is too short.

- Option 3: 50 feet is not the longest.

- Option 4: 30 feet is not the longest.
