Question

There is a floating cubic-formed matter in water. Half of it inside
and the other half outside of water.
1) If we translate it to the moon, haw amount of it will be
inside water?
2) What about, when the same matter is on a planet with gravity
twofold of earth.
3) What is the situation to water at zero gravity?
(Suppose all other conditions as it in the earth.)

Answer 1

Any object floating on water displaces a volume of water equal to its own weight. The volume of the object must not change (inflate or deflate) when moved to a new (space) venue. Assume you are within an earth colony on the moon providing atmospheric control (otherwise the water may evaporate). The object and the water would lose weight in the same proportion and the object should float in the water to the same level as on earth. That should also be true on a planet with twice the gravitational attraction at its surface. The situation would be quite different at zero gravity (perhaps within a satellite circling the earth?). Both the water and the object would float freely within the capsule and the object can not displace water and float.

Answer 2

1&2 should both be the same because the gravity affects everything differently, in the same proportion.
3 could be anything-there is no gravity holding either in place.

Answer 3

Oh my...I can see why no answers yet...

Hope you didn't need the answer for a homework problem.

Good luck and let me know the answers.
