Final answer:
A worksheet window can have a total of 17,179,869,184 cells. The label for the cell in row 1, column 16,384 is XFD.
Step-by-step explanation:
A worksheet window in programs such as Microsoft Excel can contain up to 1,048,576 rows and 16,384 columns, which means there can be a total of 17,179,869,184 cells in a single worksheet.
As for the columns, they are labeled alphabetically, starting with A for column 1 and continuing with double letters after Z (the 26th column), such as AA, AB, etc. For the 16,384th column, this labeling system continues through to using triple letters. The label for the cell in row 1, column 16,384 would be XFD, as XFD is the last column label in this sequential system.
