Final answer:
The volume of an object can be found by rearranging the formula for density, resulting in the formula v = m/d. This suggests that the volume can be calculated by dividing the mass of the object by its density.
Step-by-step explanation:
The formula for density is described as d = m/v, where d is the density, m is the mass of the object, and v is the volume of the object. When solving for v in terms of d and m, the equation can be rearranged by multiplying both sides by v and dividing both sides by d. This gives us the formula v = m/d, which is your option a). This formula means that the volume of an object can be calculated by dividing its mass by its density.
