The discussion revolves around determining the volume of a secret cavity within a brass sculpture, utilizing the sculpture's weight in air and submerged in water, along with its density.
Participants are exploring various aspects of the problem, including the implications of the buoyant force and the assumptions regarding the cavity's contents. There is no explicit consensus yet, but some guidance on relevant principles has been mentioned.
There is uncertainty about the contents of the cavity, which may affect the calculations. Participants are also navigating the implications of Archimedes' principle in this context.
A small sculpture made of brass (density = 8470 kg/m cubed) is believed to have a secret central cavity. The weight of the sculpture in air is 15.76N. When it is submerged in water, the weight is 13.86 N. What is the volume of the secret cavity?
