Answer:
29.5 g/cm^3
OR
29500 kg/m^3
answer varies depending on what "correct units" means for your school/board
Step-by-step explanation:
D = mass/volume
therefore;
825/28
29.5 g/cm^3
OR
825 * 10^-3 = 0.825 kg (to convert from g to kg)
28 * 10^-6 = 2.8 * 10^-5 m^3(to convert from cm^3 to m^3)
D = mass / volume
therefore;
D = 0.825/(2.8 * 10-5)
= 29500 kg/m^3
