The mass of a substance can be derived from its density. Density is equal to mass per volume, so if volume is known, divide volume by density to get mass.

Not enough information. To calculate mass, you would need volume and density (mass = volume x density).
You cannot calculate the volume of an object using only the density; you must also calculate the mass.You can calculate the mass by simply weighing the object.Density = Mass / VolumeTherefore Volume = Mass/Density.If you cannot be bothered to calculate the mass, simply measure the object. Multiply the length, times the width, times the height and you have the volume.
mass= density*volume
-- Use the length of the cube's side to calculate its volume. -- Divide the cube's mass by its volume. The quotient is its density. The density is 6.25 g/cm3 . Now that you know the answer, you can fill in the missing steps, and learn something at the same time. Is that cool or what !
The shape of an object is not enough to calculate its density. You also need its mass and then Density = Mass/Volume.
