Question

A solid block of plastic has the following dimensions and properties at 20.0 oC: • L = 42.11 cm, W = 37.55 cm, and H = 19.36 cm; • ρ = 917 kg/m3

A. Calculate the volume and mass of the plastic at 20.0 oC.

B. The block is placed in a fresh water lake. Determine if the block floats. If the block sinks to the bottom, calculate the force the bottom of the lake exerts on the block. If the block floats, how much of the block is submerged?

C. If the block floats, find how much “cargo” the block can support before sinking. If the block sinks, find the volume of the block necessary to float and explain how to accomplish this volume.
