Hi, Raul,

if you have to useallcubes to form a rectangle, then you'll get 6 different rectangles: Calculate all divisors of 372 and you get:

1. rectangle: 1 * 372 or 372 * 1

2. rectangle: 2 * 186 or 186 * 2

3. rectangle: 3 * 124 or 124 * 3

4. rectangle: 4 * 93 or 93 * 4

5. rectangle: 6 * 62 or 62 * 6

6. rectangle: 12 * 31 or 31 * 12
