Final answer:
The mass of a 10.0 cm³ cube of lead is 113 g, calculated by multiplying the density of lead (11.3 g/cm³) by the volume of the cube.
Step-by-step explanation:
To find the mass of a lead cube with a given volume, we need to use the density of lead. We have the cube's volume (10.0 cm³) and the density of lead (11.3 g/cm³, as per given information).
By multiplying the density by the volume, we'll find the mass according to the formula mass = density × volume. Therefore, the mass of the lead cube is mass = 11.3 g/cm³ × 10.0 cm³ = 113 g.
