The volume of that block is (20 x 30 x 15) = 9,000 cm3
The density of lead is 11.34 gm/cm3
The mass of the block is (11.34 gm/cm3) x (9,000 cm3) = 102,060 grams = 102.06 kg
That little grey thing sitting there, only 7.9 inches x 11.8 inches x 5.9 inches,
weighs 225 pounds! I am astonished. But the arithmetic checks out.
