Final answer:
To calculate mass using density and volume, use the formula: Mass = Density x Volume.
Step-by-step explanation:
The mass of an object can be calculated using density and volume by using the formula:
Mass (m) = Density (D) x Volume (V)
For example, if you have a substance with a density of 2 g/cm³ and a volume of 10 cm³, you can calculate the mass by multiplying the density and volume:
Mass = 2 g/cm³ x 10 cm³ = 20 grams
