* Density is the key: Volume and mass are related through density. Density is the amount of mass per unit volume. The formula is:
* Density (D) = Mass (M) / Volume (V)
* You need density: To find volume (V) using mass (M), you need to know the density (D) of the object.
Here's how to solve for volume if you know density and mass:
1. Rearrange the formula: V = M / D
2. Plug in your values: Substitute the mass (M) and density (D) into the formula.
3. Calculate: Divide the mass by the density to get the volume.
Example:
* You have a block of aluminum with a mass of 27 grams. Aluminum has a density of 2.7 g/cm³.
* V = M / D = 27 g / 2.7 g/cm³ = 10 cm³
In conclusion: You need to know the density of the object to calculate its volume from its mass.
