A particular uranium alloy has a density of 18.75 g/cm3.
a. What volume is occupied by a critical mass of 49 kg of this alloy?
b. The critical mass can be decreased to 16 kg if the alloy is surrounded by a layer of natural uranium (which acts as a neutron reflector). What is the volume of such smaller mass?
