ANSWER


197 {in}^(2)

EXPLANATION

The area of the two tra-pezoidal faces


= 2 * (1)/(2) * (9 + 5) * 5 = 70 {in}^(2)

The area of the 5 by 6.4 rectangular face


= 6.4 * 5 = 32 {in}^(2)

The area of the two square faces


= 2(5 * 5) = 50 {in}^(2)

The area of the 9 by 5 rectangular face is


= 9 * 5 = 45 {in}^(2)

The surface area of the design is:


70 + 32 + 50 + 45=197 {in}^(2)
