in the opening scene of the movie Raiders of the Lost Ark, Indiana Jones tries to remove a gold idol from a booby-trapped pedestal. He replaces a gold (D = 19.32 g/cm³) idol of dimensions 5.0 inches by 5.0 inches by 5.0 inches with a bag of sand of approximately double the volume with sand (D = 3.65 g/cm³). Is the bag of sand really equal to the gold idol or will Dr. Jones set off the trap? Explain your answer and include a mathematical explanation. ML Cm3
