9/26/08 **//Densities of materials//** Our density was 2.8375. We think it is aluminum. The length of this object is 4 centimeters tall and 2 centimeters wide. Using water displacement, we figured out the density (which is stated above). The metal block was a shiny silver color. we found out the density by dividing mass by volume and got about 22.53. __//**Derived Quantities**//__ : formulas volume = length x width x height density = mass / volume
