ensity of solid gold is 19.3 g/cm3 and the density of sand is 3.00 g/cm3, what volume of sand must the thief use?
Hey Wendy! Here is the solution to your problem. First, find the volume of the gold cylinder. Then, convert that volume to grams of gold. Notice that the grams of gold must equal the grams of sand in order for the alarm to not go off.
Using the grams of sand, calculate the volume of sand using the density of sand given. Hope this helps! Let us know if you have any other questions :)
