A uniform solid cube material 10cm on each side of mass 700g is submerged in water. which of the following best described the behavior of the cube water?
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
Verified Correct Answer: B.
Physical Principles & Numerical Solution
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
