*physics *without using your spring scale, estimate the order of magnitude of the mass of your calculator in grams from what you judge to be its size, using the fact that the density of water is 1 g/cm3. assume that the density of water is about the same as the density of your calculator.1 g  102  g104  g106  g

We consider that my calculator has the following dimensions (approx) : Length = 14 cm Width = 7 cm Heigth= 2 cm Then the volum of the calculator will be V=Length x Width x Height = 196 cm3 If we assume that my calculator has the same density of water, that is 1 g/cm3 that means my calculator mass is: M = 196 cm3 * 1 g/cm3 = 196 grams
