The power to which the base quantities are raised to represent a derived quantity.

Vedclass · Answer

(B) Dimension: The power or exponent to which base quantities are raised to represent a derived quantity is called the dimension of that quantity.Example: $	ext{Volume} = 	ext{length} 	imes 	ext{breadth} 	imes 	ext{height}$.Since length,breadth,and height are all types of lengths,their dimensional representation is $L$.$	ext{Volume} = L 	imes L 	imes L = L^{3}$.Thus,the dimension of volume is $3$ in length.
