Answer:
7 cups of water
Step-by-step explanation:
Every 8 hours equals one cup of water.
56 hours divided by 8 hours is 7 cups of water.
The only thing that we have to do in this problem is to
convert the units.
We know that:
1000 g = 1 kg
100 cm = 1 m
Therefore:
density = (2.7 g / cm^3) * (1 kg / 1000 g) * (100 cm /
m)^3
<span>density = 2700 kg / m^3</span>
