The answer
according to the figure, we can solve this problem only by applying sines rule:
that is 
sinA/a  = sinB/b = sinC /c
As we observe,  sin A /54  = sin B/27 = sin C/ c, and c = AB
besides, sinC > sinB > sinA  , so the only answer possible is 
<span>27 < AB < 81</span>

Pyramid
volume=base area times height times 1/3
or 
length times widht times height times 1/3
base area=3
3 times height iems 1/3
height=4
3 times 3 times 1/3=4 times 1/3 times 3=4 times 1
each pyramide=4 in volume
so 
x pyramids =alabaster volume
divide by pyramids
x=alabaster/pyrimds
alabaster=576
pyramids=4
divide 
576/4=144
the artis can make 144 pyramids
