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.
It would be the same, 1,000,000, as each one's length is 1cm
A line of a million centimeter cubes would be 10,000 meters long when converted into meters, as there are 100 centimeters in a meter.
A cube made from 8 smaller cubes would have a greater volume than a long row of cubes if the row consists of fewer than 8 cubes. The volume of a cube is calculated as the side length cubed, and since 8 cubes can be arranged to form a larger cube, their combined volume will exceed that of a straight line of cubes. If the row also consists of 8 cubes and is arranged in a straight line, their volumes would be equal, but the cube would occupy a smaller space due to its three-dimensional shape.
24 cubes would be it.
We built a 30' long line in class today :)
1 million centimetres!
Years.
1 million centimetres = 10,000 meters = 32808.399 feet
no
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.
Well, isn't that just a delightful little stack of cubes you're imagining! To build a stack that is 3 cubes long, 2 cubes high, and 4 cubes deep, you would need a total of 24 cubes. Just imagine all the happy little details you could add to each cube as you stack them up!
