A solid rectangular prism is gently lowered into fresh water and then released. The prism has measured edge lengths of 2.0cm×3.0cm×5.0cm and a mass of 0.270kg.
(a) Calculate the volume of the prism.
(b) Determine the average density of the prism.
(c) Based on your calculation, state whether the prism floats or sinks when released in water and justify your conclusion.
(d) The prism is now held completely submerged and attached to a vertical spring scale. Calculate the reading of the scale while the prism is at rest under water.
