What is the length and width of a textbook?

The dimensions of a typical textbook can vary depending on the specific book and its publisher. However, approximate average dimensions for a standard-sized textbook might be:

- Length: Around 22 - 23 centimeters (8.7 - 9.1 inches).

- Width: Approximately 17 - 18 centimeters (6.7 - 7.1 inches).

These measurements are just general estimates, and actual dimensions may differ based on the particular textbook.
