a rectangular container with base 9 by 11cm has a height of 38.5cm.
assuming that water expands 10 percent when it freezes,
determine the depth to which the container can be filled so that when the content freeze, the ice does not go above the top of the container.
:
Let d = the height of the water to satisfy this requirement
1.1d = 38.5 cm
d = 38.5/1.1
d = 35 cm height of the water
:
:
Check this,
find the vol of the water: 9*11*35 = 3465 cu/cm
find the vol of the container 9*11*38.5 = 3811.5 cu/cm
%283811.5-3465%29%2F3465 = .1 which is 10%
