Dave wants to get a heavy rectangular box from point A to point B by repeatedly turning it over. The width of the box is 30 \text{ cm} and its length is twice its width.
The diagram shows the distance travelled after the first and second turn. After 3 turns, what distance along the ground has been covered starting from point A?
If the distance from point A to point B is 1620 \text{ cm}, how many times must the box be turned?
