7. A cube of wood having a side dimension of 20.0 cm and a density of 650 \( \mathrm{kg} / \mathrm{m}^{3} \) floats on water. (a) What is the distance from the horizontal top surface of the cube to the water level? (b) How much lead weight must be placed on top of the cube so that its top is just level with the water?

Step 1
The side of the cube is 20.0 cm, which is 0.2 m. \[ V = \text{side}^3 = (0.2 \, \text{m})^3 = 0.008 \, \text{m}^3 \] Show more…
