The formula for the surface area of a rectangular prism is given as:
Surface Area = 2lw + 2lh + 2wh
Given the dimensions of the textbook:
length (l) = 14 in
width (w) = 2 in
height (h) = 9 in
Substituting the values into the formula:
Surface Area = 2 * 2 * 14 + 2 * 2 * 9 + 2 * 14 * 9
Surface Area = 56 + 36 + 252
Surface Area = 344 in^2
Therefore, the surface area of the textbook is 344 in^2.
