Density is defined as mass per unit volume, or D = m/v. Solve the density equation for the variable v: *
v = D + m
v = D/m
v = D * m
v= m/D

v = m/D

Explanation:

Density is defined as the mass per unit volume, or D = m/v. Solve for Density equation for the variable v:

With this we are making v Which represents volume the subject so;

With this you multiply both sides by ;

And then the v will multiply the d making it

“vd” and the ‘v’ will cancel the v making it;

So then we divide both sides by d to make v the subject.

So the d cancels the d leaving;
