the relative density of an alloy is 6.5.find the mass of the solid alloy cube of side 20cm.what volume of the alloy has a mass of 13kg

bobpursley,
if relative density (to water) is 6.5, then the actual density is 6.5g/cm^3
mass= density*volume= 6.5g/cm^3 * (20cm)^3
volume= mass/density= 13000/6.5 cm^3
