Answer:

24 ways.

Step-by-step explanation:

  1. You can put any of the first cards in box A, you can do this in 4 different ways.
  2. For the second card, you'll have 3 options to put it in box B.
  3. For the third card, you'll have 2 options to put it in box C.
  4. For the last card, you'll only have 1 option (the remaining card will have to go to box D).

Therefore you have 4 x 3 x 2 x 1 = 24 ways of place the cards in the boxes.
