A student uses a displacement can to determine the volume of a metal cube. The can is not filled right up to the spout before the cube is lowered in. What effect does this have on the calculated density of the cube?
The density is too low because the volume collected is too large
The density is unchanged because the mass has not been affected
The density is too high because the volume collected is too small
The density is too high because the volume collected is too large
