Final answer:
The height of a building refers to its vertical measurement from the ground to the roof. In the given example, with 39 stories at an estimated 4 meters each, the building's height would be approximately 156 meters. Option C is correct.
Step-by-step explanation:
To estimate the height of a building, one can use the number of stories and the average height of one story. Given that there are 39 stories in the building, and assuming the height of one story is approximately equal to the length of two adult humans, each being about 2 meters tall, the calculation is straightforward. You multiply the number of stories by the height of one story.
Using this method, the height of one story would be 2 meters (height of an adult human) times 2, giving us 4 meters per story. Multiplying 4 meters by the 39 stories results in an estimated total height of 156 meters for the building.
The height mentioned in the context of buildings generally refers to the measurement from the ground (sidewalk) to the topmost architectural detail (roof). Therefore, when the student expresses amazement at the height of the building, it refers to how tall the building is.
