Question

A thief uses a bag of sand to replace a gold statue that sits on a weight sensitive alarmed pedestal. The bag of sand and the statue have exactly the same volume 1.75 L. Assume that the mass of the bag is negligible. Calculate the mass of each object.

Answer 1

Answer:

No, the thief didn't set off the alarm. As the mass of the gold statue and the bag of sand is different, the alarm clock will start ringing once the statue is replaced with the bag of sand. Thus, the thief screwed up the operation.
