Question

The equation d = can be used to calculate the density, d, of an object with mass, m, and volume, V. Which is an equivalent equation solved for V?

Answer 1

d = m / V

Multiply both sides by V

dV = m
Divide both sides by d:-

V = m /V Answer

Answer 2

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.
