Which equation describes the mass of an object in relation to its volume and density

M=d/v
M=d x v
M=d/v
M=d+v

The equation that describes the mass of an object in relation to its volume and density is:

M = d x v

The equation that describes the mass of an object in relation to its volume and density is:

M = d x v

Where:
M represents the mass of the object
d represents the density of the object
v represents the volume of the object.
