Since the required units is gm/cm^3, first we will convert kg into grams. 15 kg = 15 x 1000 = 15000 grams of iron
Density can be calculated using the following rule: density = mass / volume Since both mass of volume are given, so we will just substitute in the equation to get the density. density = 15000 / 1910 = 7.8534 gm/cm^3
