Which equation describes the mass of an object in relation to its volume and density?
1. m=DV
2. m=VD
3. m=D+V
4. m=D×V
1. m=DV
The correct equation that describes the mass of an object in relation to its volume and density is:
1. m = D × V
The equation that describes the mass of an object in relation to its volume and density is option 1: m = DV.
To understand why, let's break down the variables:
- "m" represents the mass of the object.
- "D" represents the density of the object, which is defined as mass per unit volume (mass/volume).
- "V" represents the volume of the object.
To find the mass (m), we can multiply the density (D) by the volume (V). This is because the density gives us the mass per unit volume, so by multiplying the density by the volume, we get the total mass.
Hence, the equation m = DV is the correct one to describe the relationship between mass, volume, and density.
