The density is mass per volume.
Volume comes from the three lengths multiplied:
50x30x20=30000 cubic cm = 30 litres = 0.03 cubic meter.
Thus the density is: 180kg/0.03 cubic meter = 6000 kg/cubic meter.

density = mass/volume.
volume = length x width x height.
Therefore:
1) multiply 50 x 30 x 20
2) divide 180/3000
3) and that's your answer.

density is mass divided by volume.
They give you the mass.
You can figure out the volume ('cause it's shaped like a box and they tell you the length, width and height.)
Divide the mass by the volume.
That's the density.
