Yes, if two objects have the same volume and density, they will also have the same mass. Here's why:

* Density: Density is a measure of how much mass is contained within a given volume. It's calculated as:

* Density (ρ) = Mass (m) / Volume (V)

* Equal Density & Volume: If two objects have the same density (ρ) and the same volume (V), the equation above tells us that their masses (m) must also be the same.

In simpler terms: If you have two containers of equal size filled with the same material (like water), they will weigh the same because they have the same amount of "stuff" packed into the same space.
