Rami has 5 choices to paint the lid, then she has 4 choices to paint sides and then she has 3 choices to paint the base. Thus, the total number of different possible color schemes are there for Rami to paint each box using these colors and rules = 5*4*3 = 60 schemes

The correct answer: C

Hope this helps!

Since there are a total of 5 colors and order matters, the total number of ways to paint the boxes using 3 colors is:

5P3 = 5 x 4 x 3 = 60

Answer: C
