To measure the mass of a metal cube. First find it's volume, V = L (length) x W (width) x H (height), since it's a cube the L, W, and H are all the same so, V= L^3= H^3= V^3. Then you look up the...
Assuming the metal is pure, its density should provide a clue as to its identity. Density = mass/volume = 15.4 /(1.2)^3 = 8.9 g/cm3From density of metals table:Copper has a density similar at 8.96...
