There are several potential problems that might arise from Mal's calculations:

1. Rounding Error: The height of one stair is given as "approximately" 18.1 cm. Since it is an approximation, small deviations in actual stair height could compound over multiple stairs and flights, leading to significant errors in the total height.

2. Neglecting Gaps or Platforms: Stairs often include gaps between flights (e.g., landings or platforms between sets of stairs). If these have not been accounted for, the total height estimate for the building may be too low.

3. Consistency of Stair Height: Mal assumes all stairs have an identical height of 18.1 cm, but in real construction, there could be variations. Small differences in stair height from one flight to another could alter the total height.

4. Cumulative Error over Multiple Flights: Mal calculates the height for eight flights of stairs based on the height of a single stair. Even a minor discrepancy in the individual stair height can lead to a significant difference when multiplied across 128 stairs (16 stairs per flight for 8 flights).

5. Building Design: Mal is assuming that the height of each flight directly contributes to the height of the building. In reality, additional structural elements such as ceilings, floors between stories, and mechanical spaces would need to be considered in the building's total height.

Here are 5 questions to deepen your understanding of the topic:

1. How might you more accurately measure the height of a stair to minimize rounding error?
2. How can you account for landings or platforms in your height calculations?
3. What methods can be used to ensure that the stairs' height remains consistent across different flights?
4. How could you correct for variations in stair height when calculating the total height of a building?
5. What other building elements besides stair height should be considered when calculating the total height of a structure?

Tip:

When performing large-scale calculations involving many repeated measurements, it’s important to use precise measurements and account for any cumulative effects of small errors.
