Question

Habitable space, hallways, corridors, bathroom, toilet rooms, laundry rooms and portions of basements containing these spaces shall have a ceiling height of not less than ____ feet.

1) 6
2) 7
3) 8
4) 9

Answer 1

The minimum ceiling height required for various spaces in residential buildings, like hallways and bathrooms, is 7 feet. This ensures proper space utilization for comfort and safety. Calculating the mass of air in a house is possible using the volume and density of air, but air itself cannot be lifted like solid objects.

Step-by-step explanation:

The question pertains to the minimum ceiling height required for habitable space, hallways, corridors, bathroom, toilet rooms, laundry rooms, and portions of basements containing these spaces. According to most building codes, the minimum ceiling height is 7 feet. This requirement ensures adequate space for air circulation, lighting, and the overall comfort and safety of the occupants.

In terms of the mass of air within a house, using the dimensions provided (a floor area of 150 m² and a floor-to-ceiling distance of 2.5 m), we can calculate the volume of air and, subsequently, its mass. To find the mass of the air, we would use the volume of the house and the density of air (approximately 1.225 kg/m³ at sea level and room temperature). However, the mass of air is not something that can be 'lifted' as it is a gas distributed throughout the house. Comparing it to 'bags of rocks' is metaphorical; the real weight of the air would be far too dispersed to lift in the traditional sense.
