How do the units of volume differ from the units of area?
Length is a one-dimensional quantity, area is a two-dimensional quantity, and volume is a three-dimensional quantity. Length is defined in terms of linear units, feet (ft) and meters (m), for example. Area is defined in terms of square units, such as square feet (sq ft or ft2) or square meters (sq m or m2). Volume is defined in terms of cubic units, such as cubic feet (cu ft or ft3) or cubic meters (just m3). By the way, saying that a surface has an area of 100 square feet (sq ft) is the same as saying it has an area of 100 feet squared (ft3). Note that there are other units of area that don't involve the words square or squared. Some examples are acre, are, and hectare. The last two are metric units. Also note that there are units of volume that don't involve cubic units. Some examples are ounce, pint, quart, gallon, milliliter, and liter. Some people refer to those units as units of "capacity," but they are essentially units of volume.
How many cc in 80 inches?
Actually none! Why? "cc" measures the quantity in volume while "inches" measures the quantity in length. You can't convert "length" units to "volume" units since they are not related to another.
Why is the fundamental value of a quantity not changed when the quantity is multiplied by a conversion factor?
the conversion factor merely changes the number in such a way that it fits the new units the physical quantity is not changed
How many standard units are there?
Without knowing the specific subject or sub-category of that subject it is not possible to give a numeric answer.There are several systems of measurement each with different standard units. The most commonly used is the SI system, however, all rely on defined units and others that are derivedfrom these.Defined units would be for such things as mass, length and time.Derived units would be area, volume and speed.These are only examples.There are also units with no physical quantity which are used in certain areas which are purely comparative.An example would be a persons IQ for instance
What is the volume of 10 units 4 units and 3 units?
Volume = 10*4*3 = 120 cubic units
