Answer:
Mercury<Venus<Earth<Mars<Jupiter< Saturn< Uranus<Neptune
I can not solve the problem if I do not have the mass.
-- volume = (length)(width)(height)
-- Since the cube is a cube, its three dimensions are all the same number.
Volume = (2.5cm)(2.5cm)(2.5cm)
Volume = 15.625 cubic cm
-- density = (mass) / (volume)
Density = (1129.56g) / (15.625cm^3)
Density = 72.3 g/cm^3
(roughly 3.2 TIMES the density of the most dense naturally occurring substance on Earth)
If they become closer, it is increased, and if the objects become farther away is decreased.
