The word identity is a mistake. The question asks for the density of a cube of metal with the measures and mass given.
Density = mass / volume
mass = 35.45 g
volume of a cube = (length of the side) ^ 3 = (1.5 cm)^3 = 3.375 cm^3
Density = 35.45 g / 3.375 cm^3 = 10.50 g / cm^3.
Answer: 10.50 g / cm^3
