750 feet tall how many stories would the building have
The correct answer and explanation is:
Correct Answer: A building that is 750 feet tall would typically have approximately 62 to 70 stories, depending on its design and purpose.
Explanation:
To estimate how many stories a building has based on its height in feet, we need to understand the average height per story. This varies depending on the building’s function:
- Residential buildings: Each story averages 10 feet (due to lower ceilings and mechanical requirements).
- Commercial/office buildings: Each story averages 12–14 feet (to accommodate higher ceilings, HVAC systems, lighting, etc.).
- Mixed-use or luxury buildings may have even taller floors.
Step-by-step Estimation:
1. Using residential average (10 feet/story):
750 feet10 feet per story=75 stories\frac{750 \text{ feet}}{10 \text{ feet per story}} = 75 \text{ stories}
2. Using commercial average (12–14 feet/story):
- At 12 feet/story:
75012≈62.5 stories\frac{750}{12} \approx 62.5 \text{ stories}
- At 14 feet/story:
75014≈53.6 stories\frac{750}{14} \approx 53.6 \text{ stories}
Most Realistic Estimate:
Given that many tall buildings are mixed-use or commercial in nature and that an average story is often assumed to be about 11–12 feet, a commonly accepted rule of thumb is:
1 story ≈ 11–12 feet
So: 75012≈62.5 stories\frac{750}{12} \approx 62.5 \text{ stories}
Conclusion:
A 750-foot-tall building would have:
- About 75 stories if residential
- About 62–63 stories if commercial
- Around 60–70 stories in general, depending on design
This is only an estimate, as actual story counts can vary based on architectural design, ceiling height, mechanical systems, and building purpose.
