The relative Density of an alloy is 65.(a) find the mass of a solid alloy cube of side 20cm.(b) what vol of the alloy has a mass of 13kg? Please explain in details

Density is not a dimensionless quantity. You have to tell us what the units are. Just saying "65" is not enough. It cannot be 65 g/cm^3. There are no alloys that dense.
