Question 755677
First calculate how many cubic meters is one tile.


One tile:  {{{1*(12/1)*(0.0254/1)*1*(12/1)*(0.0254/1)*0.02}}} cubic meters.

I did not show the units ratios, but you should fill them in to be sure that expression works. 
12 inches = 1 foot
2.54 cm = 1 inch
100 cm = 1 m
0.01 m = 1 cm.


Now how many of THOSE cubic meters are in the one big block of 1 cubic meter stone?
