1 small cube = 1 small cube
10 small cubes = 1 long
10 longs (or 100 small cubes) = 1 flat
100 flats (or 1000 small cubes) = 1 large cube
13,450 needs to be divided into groups (by number). Separate by thousands, hundreds, and tens.
There are 13 thousands in 13,000. That leaves 450 remaining. 450 is 4 hundreds and 5 tens.
1 large cube is 1000 small cubes. 1000 * 13 = 13,000. You need 13 cubes, with a total of 450 remaining.
100 small cubes is 1 flat. 100 * 4 = 400. You need 4 flats, with 50 remaining.
10 small cubes are 1 long. 10 * 5 = 50.
You need 13 cubes, 4 flats, and 5 longs.
