They are\xa0represented by square brackets\xa0around the quantity.\tDimensions of the 7 base quantities are – Length [L], Mass [M], time [T], electric current [A], thermodynamic temperature [K], luminous intensity [cd] and amount of substance [mol].Examples, Volume = Length x Breadth x Height = [L] x [L] x [L] = [L]3\xa0= [L3]Force = Mass x Acceleration = [M][L]/[T]2\xa0= [MLT-2]\tThe other dimensions for a quantity are always 0. For example, for volume only length has 3 dimensions but the mass, time etc have 0 dimensions. Zero dimension is represented by superscript 0 like [M0].Dimensions do not take into account the magnitude of a quantity<br>There are three types of dimensions 1. Macroscopic2.
