Answer:

234

Step-by-step explanation:

surface area = 2( LW + LH + WH)

where L = Length = 9

          W = Width = 2

          H = Height = 9

plugin values into the formula:

surface area = 2 ( LW + LH + WH)

                     = 2 ( 9*2  + 9*9  + 2*9 )

                     = 2 ( 18 + 81 + 18 )  

                     =  2 (117)

                     = 234
