A rectangular tank with a square base of side 5m contains water to a depth
of 4 m.
A solid cube of edge 3m is placed at the bottom of the tank.
What does the level of water rise to?
:
Find the vol of the water: 5*5*4 = 100 cu/m
Find the vol of the cube : 3^3 = 27 cu/m
Find the vol with cube in the water: 127 cu/m
:
Let h = height of the water with the cube in there:
5*5*h = 127
h = 127%2F25
h = 5.08 m is the height of the water with cube in there
