Answer:
69 in^2
Step-by-step explanation:
I will assume you meant the following:
length: 9 in
width: 2 in
height: 1.5 in
The area of (each) the top and bottom is L * W = (9 in)(2 in) = 18 in^2; twice that includes the total area of top and bottom and is 36 in^2.
The total area of the ends is 2(2 in)(1.5 in) = 6 in^2
The total area of the front and back is 2(9 in)(1 1/2 in) = 27 in^2
Thus, the total surface area is (36 + 6 + 27) in^2, or 69 in^2.
