A building has a floor space of 16.7 m (55 ft) by 45 m (150 ft) with a common core measuring 9.17 m (30 ft) by 13.7 m (45 ft). How many individual can be provided in the usable floor space?

Question

Quizplus · Accepted Answer

First, we need to calculate the total usable floor space by subtracting the area of the common core from the total area:

Total area = (16.7 m x 45 m) = 751.5 m^2
Common core area = (9.17 m x 13.7 m) = 125.56 m^2
Usable floor space = Total area - Common core area = 625.94 m^2

We can assume that each person will require about 4 m^2 of floor space (which is a common standard for office/workplace designs), so we divide the total usable floor space by 4:

Number of people = Usable floor space / 4 = 625.94 m^2 / 4 m^2 = 156.48

However, we can only have whole people, so we round down to get the final answer:

Number of people = 156

The closest answer choice is C (69), so that is the correct answer.
