Question 1210256
.
The volume of water increases by 8 1/2% when freezing. 
Determine amount of space   water will occupy when frozen the volume is 1085 cu. ft.

Unsure how to solve.
~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
The problem says that if the volume of water is x, then the corresponding volume 
of ice is 1.085x, and vice versa.

It is true for freezing process; for thawing/melting process, the liquid volume returns to its original value.


        // These facts are well known.  Normally, students learn them 
        // in middle school in their 6th or 7th grade, when they study Science.


Also, the problem gives the volume of ice 1085 cu. ft, and asks to find the corresponding volume of water.



    It means that the problem itself is equivalent to this equation

        1.085x = 1085  for the solid volume,

    from which you should find the liquid volume  x.



So,  x = {{{1085/1.085}}} = 1000 cu ft.

At this point, the problem is solved in full.



To understand such problems in full and to solve them successfully,
the important first step is to make their formulation as straightforward as possible,
without losing their meaning.
