A golden-colored cube is handed to you. The person wants you to buy it for 50000 php, saying that it's pure gold. You pull out your old geology text and look up gold in the mineral tabl, and read that its density is 19.3 g/cm^3. You determine the weight of the cube while in air and while completely submerged in water. The weight of the cube is 45 N in air and 42 N in water. What is the denisty of the cube?   a. 2.9 g/cm^3 b. 19.3 g/cm^3 c. 15.0 g/cm^3 d. 28.9 g/cm^3
