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...
You would need to use a Triple Beam Balance, or you could put it on a scale, and then convert the scale's measurement to grams, which is the measurement of mass.
