Answer:

Explanation:
Density is D = M/V, where D = density, M = mass, and V = volume.
- First, I would calculate the volume. For the volume, you will multiply all the values you are given along with their units.
- You would then plug the values you know into D = M/V. Your mass is 1.1kg, so D = 1.1 kg / V
- Your volume is 400 cm^3, so D = 1.1kg/400 cm^3
- Keeping the units, you would divide to get a density of 0.00275 kg/cm^3
