A. the cube will melt after a period of time
B. the cube will float
C. the cube will sink in water
D. the cube will rest at an equilibrium position in water
Correct Answer:
Option B – the cube will float
Explanation
For the uniform cube 10cm volume = 10 x 10 x 10 = 103 cm³
Mass = 700g
∴ density = (Mass)/Volume = (700)/100 = 0.7gcm−³
since the density is less than the density of water, the cube will float
