What do you mean by dimensions of physical quantity?

Each derived quantity requires proper power for fundamental quantities so as to represent it. The powers of fundamental quantities, through which they are to be raised to represent unit-derived quantity, are called dimensions. In other words, the dimensions of a physical quantity are the powers to which the base quantities (fundamental quantities) are raised to represent that quantity.

For example:

The area is the product of two lengths.
Area = Length X breadth = [L] x [L] = [L²]
Therefore, [A] = [L²] That is, the dimension of area is 2 dimension in length and zero dimension in mass and time.
Or [A] = [M⁰L²T⁰]
Similarly, the volume is the product of three lengths.
Volume = Length X breadth X height = [L] x [L] x [L] = [L³]
Therefore, [V] = [L³] That is, the dimension of volume is 3 dimension in length and zero in mass and time.
Or [V] = [M⁰L³T⁰]
Similarly, acceleration is the rate of change of velocity per unit of time.
