Respuesta :

d = m / V

Multiply both sides by V

dV = m
Divide both sides by d:-

V = m /V   Answer
Another equation to get V is mass/density. 
A way to get density is mass/volume
A way to get mass is density times mass. 
I know you didn't ask for the other equations, but I listed them to show how density, volume, and mass are related. To answer your question, to get volume you divide mass by density.
