Final answer:
The livable floor space of a home is determined by multiplying the floor area by the ceiling height, and it represents the volume of air inside. For a house with a floor area of 150 m² and a ceiling height of 2.5 m, the livable volume is 375 cubic meters, which translates to 459.375 kg of air mass. This mass is too much for a person to lift, as humans can typically lift up to 25 kg.
Step-by-step explanation:
To determine the livable floor space of a home, you primarily consider areas that are habitable and exclude spaces like garages, unfinished basements, or attics not suitable for living. In the given scenario, we start by calculating the volume of air in the house. With a typical house's floor area around 150 m² and a floor-to-ceiling distance of 2.5 m, we multiply these to find the total livable space in cubic meters, which represents the volume of air inside.
The formula to find the volume (V) is V = area × height, thus V = 150 m² × 2.5 m = 375 cubic meters. To calculate how much mass is in the air within the house, we need to know the density of air, which is approximately 1.225 kg/m³ at sea level and at 15°C. Multiplying the volume of the air by its density gives us the mass of the air inside the house: 375 m³ × 1.225 kg/m³ = 459.375 kg.
If we consider whether this mass could be lifted by a person, the answer is that it's quite impossible. Average humans can lift up to 25 kg comfortably, so lifting 459.375 kg at once, as if it were bags of rocks, would not be feasible. Reflections on the floor plan and housing configurations serve to illustrate how housing designs cater to specific lifestyles and societal roles, affecting the livable space as well.
