Final answer:
The density of lead in a cube with an edge length of 2.00 cm and a mass of 90.7 g is 11.3 g/cm³.
Step-by-step explanation:
The density of lead can be calculated by dividing its mass by its volume. In this case, the mass of the lead cube is 90.7 g and the volume can be found by multiplying the edge length by itself three times, giving us 8.00 cm³. To find the density, we divide the mass (90.7 g) by the volume (8.00 cm³), resulting in a density of 11.3 g/cm³.
