a rectangular tank 50 cm long and 25 cm wide contains 12 litres of water.
when 4 metal cubes of the same size are placed in the tank, the height
of the water level becomes 10 cm. what is the length of each edge of the cube?
~~~~~~~~~~~~~~~~~~~~~
After submerging the 4 metal cubes in the tank, the volume occupied by the water
and cubes together is 50*25*10 = 12500 cm^3.
Hence, the volume of the 4 metal cubes is 12500 - 12*1000 = 500 cm^3.
Thus the volume of each of the 4 metal cubes is 500/4 = 125 cm^3.
The size of each cube is = 5 cm. ANSWER
Solved.
