Ann made a 3 -step staircase using 18 toothpicks as shown in the figure. How many toothpicks does she need to add to complete a 5 -step staircase?

Verified Answer :

She will need 30 toothpicks

All you have to do is divide 18 by 3 and you will get 6, the number of toothpicks for 1 step. on the staircase. Just multiply 6 by 5 [steps] and you will get 30 toothpicks, the number of toothpicks for 5 steps.
