1) Detrmine the thickness, so you can calculate volume. Be sure to convert thickness to meters (it will be a small decimal) so volume is in cubic meters.
2) Find the density of the stone you are using in kilograms or metric tons per cubic meter and multiply.
The density of stone varies somewhat according to type, what quarry it comes from, etc.

You have 180 * 3 * 1 = 540 cubic feet.
Converting to mass, 540 ft^3 * 120 lbm / ft^3 = 64,800 lbm
With 2000 lbm per ton, you would need:
64,800 lbm * 1 ton/2,000 lbm = 32.4 ton of crushed rock.

0.41 m x 0.25 m x 0.25 m = 0.0025625 m³
Various sites give various densities for marble block; as a natural materuial, it varies. The range appears to be 2.6  2.9 t/m³; I'll use 2.75 t/m³ or 2750 kg/m³.
One piece at the above volume is 7.05 kg. If you have 12 pieces, that's 84.6 kg.
