The potential energy on the moon would be 1/6 of the potential energy on Earth
Explanation:
The potential energy of an object is the energy possessed by the object due to its position in a gravitational field, and it is given by

where
m is the mass of the object
g is the strength of the gravitational field
h is the height of the object above the ground
In this problem, the potential energy of the object on the Earth is

On the Moon, the gravity is

Therefore, if the same object (same mass) is placed at the same height
on the Moon, its potential energy would be

Answer:
The balloon
Explanation:
Since there are 100 cm or 1000 mm in a meter, you can rewrite the dimensions in the following way:
A cube of metal with a volume of 10,000 mm^3
A spherical balloon with a volume of 50,000,000 mm^3
A sample of water with a volume of 1,000 mm^3
Therefore, the balloon clearly has the most volume. Hope this helps!
