Five people per 1000 square feet are allowed to enter a building Whose total dimensions is 180,000 square feet How many people can be in the building at one time

900

Step-by-step explanation:

5 people are said to occupy a 1000square feet space

That means we have to look out for how many 1000 square feets are in 180000

That would be 180000/1000 = 180

But 1000 square occupies 5 persons and there are 180 1000square which can occupy 5 people in 180 000 square.

Hence 180 * 5 = 900 is the number of persons that the hall can occupy.
