Question

Definen Dimensions obtain dimensions of physical
quantity' density)​

Answer 1

${\bold{\huge {\tt{\green {DIMENSIONS :}}}}}$

It is a physical quantity of a unit which were used as a formula in physics

dimensions of an unit defined as three basic unit M (mass) L (length) T (time)

we can obtain formula by dimensional analysis

for example

$density = \frac{mass}{volume}$

in form of dimensions we get,

$mass =[M] \\ volume = [L ^{3}]$

$density = \frac{[M] }{[ L^{3} ]} \\ density = [M][ L^{ - 3} ]$
