A solid cube just gets completely immersed in water when a 0.2 kg mass is placed on it. If the mass is removed, the cube is 2 cm above the water level. What is the length of each side of the cube ?

a) 6 cm
b) 8 cm
c) 10 cm
d) 12 cm

Answer: c
Explanation: Let the length of each side of the cube be a cm
Then, Volume of the part of cube outside water = Volume of the mass placed on it
2a2 = 0.2 × 1000
2a2 = 200
a2 = 100
a = 10
