Answer:

69 in^2

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.
