Density = Mass / Volume
Density = 19.3g / cm^3
Volume = W x L x H = 30cm x 8cm x 4cm = 960 cm^3
Solving for Mass:
Mass = Density * Volume
Mass = 19.3 * 960
Mass = 18528g
Mass = 18.528kg
Thinking of it another way...
If the bar weighs 19.3 grams for each cubic cm
...and you know you have 960 cubic cm
Just multiply to get the answer.
So the gold bar would weigh 18.528 kg.

Well, you have 30 cm x 8 cm x 4 cm of gold brick = 960 cm^3.
Now, (19.3 gm / 1 cm^3) x 960 cm^3 = 18,528 gm of gold.

18528 g or 18.528 kg, assuming the brick is not hollow...
