What kind of physical quantity is a length?
Length is a fundamental physical quantity that measures the distance between two points in space. It is a scalar quantity, meaning it has magnitude but no direction. Length is typically measured in meters in the International System of Units (SI).
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 kind of quantity is distance?
Distance is a scalar quantity that represents the physical length between two points in space. It is typically measured in units such as meters or kilometers.
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.
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.
What is the side length if a cube is 125 cubed?
The side length of a cube with a volume of 125 units cubed is: 5 units.
What kind of physical quantity is a length?
Length is a fundamental physical quantity that measures the distance between two points in space. It is a scalar quantity, meaning it has magnitude but no direction. Length is typically measured in meters in the International System of Units (SI).
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.

What kind of quantity is distance?
Distance is a scalar quantity that represents the physical length between two points in space. It is typically measured in units such as meters or kilometers.
Relation between units of lengths mass and capacity?
There is no relationship between units of mass and either length of capacity. Units of capacity are the cubed units of length.
Why are the units of mass length and time called fundamental units?
Mass, length, and time are considered fundamental units because they are independent and cannot be derived from other physical quantities. These three fundamental units serve as the building blocks for the International System of Units (SI) and form the basis for measuring other physical quantities.
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.
Does a quantity have different dimensions in different systems of units?
No. The dimensions are: Mass, Length, Time, and Charge. They transcend the systems of units. For example, speed will always have the dimensions of (Length)/(Time), regardless of the system of units.
What physical quantity is defined as units of mass per units of volume?
Density

What is the area of a cube with side of 6?
The area is six cubed.It is 216 square units of length.
What is the volume of a cube with 220.75?
10,757,271.671875 units cubed, given a side length of 220.75
