Final answer:

The mass of the air within a house with a floor area of 1,600 square feet and a ceiling height of 2.5 meters is approximately 456.20 kilograms. This is calculated using the volume of the air (space) in the house and the known density of air. Such a mass is too heavy for a person to lift as if it were bags of rocks.

Step-by-step explanation:

The question revolving around the minimum square footage for a family room is not directly related to the reference information provided. However, the reference information can help us solve a physics related problem regarding the mass of air in a typical house.

To calculate the mass of air inside a house, you would first need to determine the volume of air in the house. With a floor area of 1,600 square feet and a floor-to-ceiling height of 2.5 meters, the volume of air would be:

Volume = floor area × height

Keeping in mind the conversion factor of 1 square foot = 0.092903 square meters, we can calculate the volume in cubic meters:

Volume = 1,600 sq ft × (0.092903 m²/sq ft) × 2.5 m = 372.41 m³

Air has a density of approximately 1.225 kg/m³ at standard room temperature and pressure. So, the mass of the air in the house can be calculated using the formula:

Mass = Density × Volume

Mass = 1.225 kg/m³ × 372.41 m³ = 456.20 kg

This is equivalent to about 456.20 kilograms, which cannot be lifted by a person as if it were bags of rocks, as the mass is too great for standard human strength.
