The volume of the cylinder is L\(\pi r ^{2}\)
Which is 12 3.14 4\(^{2}\)
=602.88 cubic cm
Each piece of ice's volume is defined as 4/3\(\pi *r ^{3}\) cubic cm (volume of a sphere). With r=3/2 (since 3 cm is the diameter)
=4/3 3.14 (3/2)\(^{3}\)
=14.13 cubic cm
25 of those cumulate a total volume of 25 * 14.13 = 353.25 cm\(^{3}\)
Which means that the free space for water is 602.88-353.25=249.63 cubic cm
