It is an Rectangle Prism standing straight up with 12 cm going up.

Given that the prism is a square-based prism then when the prism is laid on its side the 72cu cm of water occupies a volume which is:-
12 x 3 x height (ht)
so 12 x 3 x ht = 72
therefore ht = 2cm
If the total height of the prism when laid on its side is 3cm then the water is 3 - 2 = 1cm from the top

If your 12 cm tall rectangular prism is is filled to a height 4 cm from the top, then it is 4/12 or 1/3 empty. If you turn it on its side, it will still be 1/3 empty and the water will be 1/3 of 3 cm from the top. Therefore, the water will be 1 cm from the top.

You need to let us know what the base of the prism is in order to know how the prism will change when it is turned on its side.
Also are we to assume it is a rectangular prism?

Because one of the three is a two not a three. So if there is two 3's and one 12. then the answer would be 108.
