Question

Ganesh and Dinga want to pack 4000-centimeter cubes inboxes. These are to be sent to a school. There are three different boxes available for packing.

• How can Ganesh and Dinga test their guesses before packing the cubes in the boxes? Discuss with your friend.

Answer 1

• 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.
