Answer:
6 cm
Explanation:
The weight of the water displaced equals the weight of the cube.
mg = ρVg
m = ρV
The mass of the cube is its density times its volume, and volume of a cube is the side length cubed.
The volume of the water displaced is the area times the depth.
(300 kg/m³ * (0.20 m)³) = (1000 kg/m³) ((0.20 m)² h)
2.4 kg = 40 kg/m h
h = 0.06 m
h = 6 cm
So 6 cm of the cube will be underwater.
