Answer 1

Answer:

Dimensional variables are those physical quantities which have dimensions of the form [M^a L^b T^c]… {where,M,L,T are fundamental physical quantities which are Mass,Length and Time respectively.

Explanation:

dimensionless quantities only have numbers. Density is defined as mass per unit volume. Volume has units m³ or cm³. Mass is represented as M.
