Diana Bush · Answer 1

The density of the lead is 11.3 g/cm³.

V = lwh = 30 cm * 20 cm * 1 cm = 600 cm³

Density = 6800 g/600 cm³ = 11.3 g/cm³

Note: The answer can have only one significant figure because that is all you gave for the height of the block. However, I calculated the density to three significant figures.
