Final answer:
The maximum reach for a 28-ft (8.5-m) ladder would depend on the desired location's height. It can reach the second-story roof, second-story windows with two rungs inside, and second-story window sills, but not the third-story roof.
Step-by-step explanation:
The maximum reach for a 28-ft (8.5-m) ladder would depend on the height of the desired location. Assuming a building with three stories, a 28-ft (8.5-m) ladder would be able to reach:
- The second-story roof: This would require the ladder to extend approximately 21 feet or 6.4 meters above the ground level.
- The second-story windows with two rungs inside: In this case, the ladder would reach the windowsill, which is typically at a height of around 9-10 feet or 2.7-3 meters.
- The second-story window sills only: This would be within the reach of the ladder, as the ladder height is 28 feet or 8.5 meters.
- The third-story roof: The ladder would fall short in reaching the third-story roof, as it would require a ladder length of approximately 42 feet or 12.8 meters.
Keep in mind that these measurements are approximations and actual buildings may have varying heights.
