If you mean that the cubes have a side length of 1 cm, and you place them side by side, you would get a length of exactly a million cm.
1 million cm is 10 km, about 6.21 miles.

The line of 1000000 centimeter cubes would be 1000000 centimeters long.
a hundred million squared
24 cubes would be it.
We built a 30' long line in class today :)
1 million centimetres!
1 million centimetres = 10,000 meters = 32808.399 feet

The answer probably is 3*2*4 = 24 unit cubes but you could also do it with 10 cubes: 2 cubes of size 2*2*2 and 8 unit cubes. The question does not require the cubes to be unit cubes.
You would be adding volumes together; whatever configuration you put them would be irrelevant then. Assuming these are all 1" cubes, you would have first a long row of 8 (1"x1"x8" total) or a cube made of cubes (2"x2"x2" total) and they both come to 8 cubic inches.
