Answer:
[tex]l\approx 1.296\,cm[/tex]
Step-by-step explanation:
The water density is approximately 1 gram per cubic centimeter, which means that 1 gram of water occupies a volume of a cubic centimeter. Hence, 2.179 grams occupies a volume of 2.179 cubic centimeters.
Let assume volume occupied by the water has a cube-like shape, whose side has the following measure:
[tex]l = \sqrt[3]{2.179\,m^{3}}[/tex]
[tex]l\approx 1.296\,cm[/tex]
