Answer 1

To find the surface area of the textbook, we need to calculate the area of each face and then add them up.

Area of the first face (2 in. × 14 in.) = 28 in²
Area of the second face (2 in. × 9 in.) = 18 in²
Area of the third face (14 in. × 9 in.) = 126 in²

Adding up the areas of all three faces, we get:

28 in² + 18 in² + 126 in² = 172 in²

Therefore, the surface area of the textbook is 172 in².
