Question 1108572: Imagine a house. Describe one-dimensional, two-dimensional, and three-dimensional parts or aspects of the house. In each case, state how you would measure the size of that part or aspect of the house—by length, by area, or by volume—and name an appropriate U.S. customary unit and an appropriate metric unit for measuring or describing the size of that part or aspect of the house. What are practical reasons for wanting to know the sizes of these parts or aspects of the house?

You can put this solution on YOUR website! NOTE: What follows is an explanation. Your teacher may favor a short answer, and you are the best judge of what kind of answer your teacher wants.
Rooms in a house are most often rectangular.
Their one-dimensional and/or two-dimensional measurements are often reported in floor plans and house-for-sale advertisements. (You may look at websites of big companies that are building houses nearby, and or at realtor group websites (look up the websites called realtor, zillow, or trulia, for example).
ONE-DIMENSIONAL ASPECTS:
In the US, one-dimensional measurements (lengths) are given in feet or feet an inches (U.S. customary units).
For example, a bedroom could be listed as 12' by 10'6" (12 feet by 10 feet six inches).
Sometimes they even list a height such as "9-foot ceilings."
A real estate agent would probably use a laser distance measurement device to measure lengths.
You would measure lengths with a tape measure, because it is less expensive, and there is probably a good one in your house.
In other countries, lengths may be listed in meters (metric unit).
TWO-DIMENSIONAL ASPECTS:
For a rectangular room, if you multiply length time width, you get the surface area of the room floor. For example, an 12' by 10'6" bedroom's area would be calculated as 12 feet times 10.5 feet = 126 square feet.
Realtors call that the "square footage,"and usually state the total for the "living area" of the house, meaning that they do not include garage area or the area of unfinished basement, or attic.
THREE-DIMENSIONAL ASPECTS:
The three-dimensional aspect of the house is the house volume.
The U.S. customary unit for volume is the cubic foot (cu ft), and the metric unit is the cubic meter.
When a large volume is filled with water, or other liquid, in the US we measure it in gallons, but that does not apply to a house.
The only volumes people mention in a house are the volume of the refrigerator (as in a 25-cubic foot refrigerator), and the volume of a water heater's tank (as in a 50-gallon gas water heater).
The cubic feet of space in a wharehouse would be important, but you never hear anyone talk about volume of a house.
I suppose the only time the volume of the house (or its rooms) matters is when thinking of heating an cooling. Even then, you would probably use the "square footage" times 8 feet, assuming ceilings are 8 feet high everywhere in the house. A house in South Florida may be advertised as "1600 sq ft under air", meaning that the air conditioning part of the house has 1600 sq ft of floor space and there is an enclosed porch Maybe you would need a bit more heating/cooling power if there are high ceilings and/or "cathedral ceilings" in some rooms. However, there would be many other considerations to determine how much heating or cooling is needed.
PRACTICAL REASONS FOR WANTING TO KNOW THE SIZES OF ROOMS AND HOUSES:
Potential buyers would be interested in the size of bedrooms and dining rooms, to figure out if the furniture they have (or they want to buy) would fit.
The price per square foot is often listed for houses that are for sale, and buyers might compare the prices per square foot for houses in the same neighborhood as one of many factors to decide which house is a better buy. For example, a buyer could compare a house listed with 2810 sqft for $350,000 and a house listed with 2008 sqft for $315,000. The prices per square foot are
 and  ,
but the buyer will also consider differences in other features of the houses, like location, lot size, garage, number of bathrooms, age of the roof and heating/cooling systems).
