Answer: The edge of the lead cube is approximately 9.57 cm.
The edge of a cube can be determined by knowing its volume. To calculate the volume of a cube, we must divide the mass of the cube by the density of the lead. Please note that the density of lead is indicated in g / cm³, and the mass of the cube is in kg. Let’s convert kilograms to grams:
10 kg = 10 * 1000 = 10000 g.
We calculate the volume:
10000 / 11.4 = 877.19 cm³.
Find the value of the edge length by extracting the cube root from the obtained value of the volume of the lead cube:
∛ 877.19 = 9.57 cm.
