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.
Is volume a base quantity?
No, volume is not a base quantity; it is a derived quantity. Base quantities, such as length, mass, time, electric current, temperature, amount of substance, and luminous intensity, are the fundamental physical quantities from which other quantities are derived. Volume is calculated from base quantities, specifically length, as it is expressed in cubic units (e.g., cubic meters).
What are measurement units called?
Measurement units are commonly referred to as "units of measure." They provide a standard quantity used to express physical quantities, such as length, mass, volume, and temperature. Examples include meters for length, kilograms for mass, and liters for volume. These units can be part of various systems, such as the metric system or the imperial system.
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.
What is density and how to find it mathematically?
Density is a physical property defined as the mass of an object divided by its volume. Mathematically, it can be expressed using the formula: ( \text{Density} = \frac{\text{Mass}}{\text{Volume}} ), where mass is measured in units like grams or kilograms, and volume in units like cubic centimeters or liters. To find the density, simply measure the mass of the object and its volume, then apply the formula.
What physical quantity has the units of length cubed?
Volume is the physical quantity that has units of length cubed. It represents the amount of three-dimensional space occupied by an object.
Why is length called a fundamental quantity?
Length is considered a fundamental quantity because it is a basic physical quantity that cannot be defined in terms of other fundamental quantities. It is used to define other physical quantities such as speed, area, and volume. Additionally, length has its own units of measurement (meter, inch, etc.) that are universally recognized and applied in various scientific disciplines.

Some people refer to those units as units of "capacity," but they are essentially units of volume.
Is volume fundamental or derived quantity?
Volume is a derived quantity because it is calculated by multiplying three lengths together in the SI system of units. The SI base units for length are meters, so volume is expressed in cubic meters (m^3). It is not considered a fundamental quantity like length, mass, or time, which are base units in the SI system.
What is meant by unit of a physical quantity in physics?
The unit of a physical quantity in physics is a standardized way to express and measure that quantity. Units give the quantity a numerical value and specify the scale at which it is being measured. Units are essential for consistency and clarity when communicating about physical quantities.
Can a quantity have units but still be dimension less give example?
Yes, a quantity can have units but still be dimensionless if the units cancel out when they are raised to the power of 0. For example, specific volume (volume per mass) has units of m^3/kg, but when you divide volume by mass, the units cancel out and it becomes dimensionless.
Why current is base quantity not a charge?
Current is considered a base quantity because it is a fundamental physical quantity that cannot be defined in terms of other physical quantities. It describes the rate of flow of electric charge in a circuit and is measured in units of amperes (A). Charge, on the other hand, is a derived quantity that depends on current and time, making current the more fundamental quantity.
Is size a quantity?
Size is a measurable quantity that represents the dimensions or extent of an object or space in physical terms. It is typically measured using standard units such as length, width, height, volume, or area.
Is volume a base quantity?
No, volume is not a base quantity; it is a derived quantity. Base quantities, such as length, mass, time, electric current, temperature, amount of substance, and luminous intensity, are the fundamental physical quantities from which other quantities are derived. Volume is calculated from base quantities, specifically length, as it is expressed in cubic units (e.g., cubic meters).
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.
What is the physical quantity which has the units Nm?
A joule has units of N-m. It is a unit of energy or work.
What refers to quantities such as area volume and velocity?
These quantities are referred to as physical quantities in the field of physics. They are measurable properties that can be described using mathematical values and units. Area and volume are examples of scalar physical quantities, while velocity is an example of a vector physical quantity.
