The equation that describes the mass of an object in relation to its volume and density is m = D × V.
To understand why this equation is correct, let's break it down:
- "m" represents the mass of the object.
- "D" represents the density of the object. Density is defined as mass divided by volume (D = m/V).
- "V" represents the volume of the object.
By substituting the density formula into the equation, we get m = (m/V) × V, which simplifies to m = m. This indicates that the mass of an object is equal to its mass, which is correct.
So, the correct equation is m = D × V.
