उत्तर
- In the first layer of box B, we can keep 11 × 11 = 121 cubes.
There are 10 such layers.
So, in box B, we can arrange 10 × 121 = 1210 cubes - In the first layer of box C, we can keep 15 × 9 = 135 cubes.
There are 10 such layers.
So, in box C, we can arrange 10 × 135 = 1350 cubes. - In all three boxes, we can arrange 1200 + 1210 + 1350 = 3760 cubes
So, 3760-centimetre cubes in total can be packed in three boxes.
