Final answer:
Charlie fills 2 boxes with chocolates, each having 7 layers of 12 chocolates. The total number of chocolates in both boxes is 168.
Step-by-step explanation:
To find the total number of chocolates that Charlie fills in the two boxes, we can calculate the number of chocolates in each box separately and then add them together. Each box has 7 layers of chocolates with 12 chocolates in each layer, so the total number of chocolates in each box is 7 * 12 = 84 chocolates. Therefore, the total number of chocolates in both boxes is 84 + 84 = 168 chocolates.
After filling the two boxes, Charlie puts them together in a larger box. Since the question does not provide any information about the size or capacity of the larger box, we cannot determine the total number of chocolates in the larger box.
