each cube has a volume of 216 cm3, therefore each edge measures (216)^(1/3)=6 cm
each cube has six faces
if they were not joined there would be 18 faces
when you put them end to end, the first cube loses 1 face, the second cube loses 2 faces, and the third cube loses 1 face for a total of 4 faces that you do not see
18-4=14 faces
each face has a surface area of 6*6=36 cm2
14*36=504 cm2
