Answer 1

To determine how many shells the crab will have, we can use the growth pattern. Starting with a 1 cm shell, each new shell is one-third bigger than the previous one. This means the size of each successive shell can be expressed as follows: 1 cm (first shell), 1.33 cm (second shell), 1.78 cm (third shell), and so on. Continuing this pattern, the crab will grow through several shells until it reaches approximately 10 cm. It will take around 7 shells to reach or exceed that size.
