Question

explain how area and volume based on fundamental quantities​

Answer 1

Both area and volume are derived physical quantities derived from fundamental physical quantity of length .

• Area = length ² = m²
• Volume = Length ³ = m³

Now , these physical quantity are directly proportional to the length of the side. Since , length is a fundamental physical quantity , area and volume are derived physical quantities.

Derived physical quantities are those that are derived from other quantities and depend on them . Since , both area and volume are not only derived from length but also depend directly on it.

Fundamental physical quantities are those which are independent of other quantities and have their self existence . There are seven fundamental quantities :

1. Mass [Kg]
2. Length [M]
3. Time [S]
4. Current [A]
5. Temperature [K]
6. Amount of substance [Mol]
7. Luminous Intensity [Cd]

Answer 2

Explanation:

Area and volume are derived physical quantities derived from fundamental physical quantity of length .

Now , these physical quantity are directly proportional to the length of the side. Since , length is a fundamental physical quantity , area and volume are derived physical quantities
