Answer:
There are often not more than one or two independent variables tested in an experiment.
Density = mass/volume
so rearranged mass = volume x density
mass = 8.920 x 45 = 401.4g
rearrange (there are 1000grams in 1kg)
volume = mass/density
volume = 1000/8.920
volume = 112.1076233cm3
Answer: If you think about it, B. would be the most reasonable answer with the given factors.
