7. Suppose that a hollow cylindrical object is floating on the surface of water. This object has a mass of 300g and is floating such that 4cm of its height is submerged under the surface of water, while 6cm of its height is above the water. How much mercury would need to be poured into this cylindrical object in order for it to sink?

Question
I need the answer in number 7 with complete solution and units based on the given problem. Also do not round off and only round off in the final answer in 3 decimal places
5. Find the weight of the floating can as shown in figure below.
4cm
Water
7cm
Ed=8cm
6. Water ice has a density of 0.91 g/cm³, so it will float in liquid water. Imagine you have a
cube of ice, 10 cm on a side.
(a) What is the cube's weight?
(b) What volume of liquid water must be displaced in order to support the floating cube?
(c) How much of the cube is under the surface of the water?
