Hi. C'mon child. Just figure the volume (30cm times 8cm times 4cm) and multiply by 19.3. Jeeze.

Take the volume of the brick first, by multiplying all the measurements together.
30cm x 8cm x 4cm = 960cm^3
Then take the density of gold, and multiply it out so that the cm^3 units cancel each other out.
(19.3g/cm^3) (960cm^3) = 18528g or 18.5 kg, which is 40.8lbs

Get the volume by multiplying 30*8*4 and multiply that value by 19.3 since that's the number of grams per cubic cm.
18528 g if I used my calculator correctly.

18.528 kilograms (lost my calculator)
30 x 8 x 4 = 960
960 x 19.3 = 18528 grams
