To calculate the volume of an object, we need to know its density and mass. The formula for volume is:

$$V = m/ρ,$$

where:

* $$V$$ is the volume in cubic meters (m^3)

* $$m$$ is the mass in kilograms (kg), and

* $$\rho$$ is the density in kilograms per cubic meter (kg/m^3).

In this case, we are given the mass of two objects, but not their densities. So, we cannot calculate their volumes. However, if we had the densities, we could use the formula above to find the volumes.
