Find the surface area of a textbook that is 2in .*14 in.*9 in. (1 point
172 ln.^ 2
252 ln.^ 2
O 50 ln.^ 2
344In .^ 2
To find the surface area of the textbook, we need to find the area of each face and then add them together.
Area of the first face = 2 * 14 = 28 square inches
Area of the second face = 2 * 9 = 18 square inches
Area of the third face = 14 * 9 = 126 square inches
Adding the areas together, we get:
28 + 18 + 126 = 172 square inches
Therefore, the surface area of the textbook is 172 in.^2.
