Study the table carefully.
- How many insects are there in Week 9?
- How many insects are there in Week 14?
- If there are 1000 insects, how many weeks have passed?
(a)
Pattern for the number of insects
Week 1: 1 x 1 x 1 = 1
Week 2: 2 x 2 x 2 = 8
Week 3: 3 x 3 x 3 = 27
Week 4: 4 x 4 x 4 = 64
Formula:
Number of insects = Week number x Week number x Week number
Number of insects in Week 9
= 9 x 9 x 9
= 729
(b)
Number of insects in Week 14
= 14 x 14 x 14
= 2744
(c)
1000 = 10 x 10 x 10
Number of weeks = 10
Answer(s): (a) 729; (b) 2744; (c) 10
