<h3>
Answer: 168 square cm</h3>
==============================================
Work Shown:
- L = 2 = length
- W = 6 = width
- H = 9 = height
The order of length, width and height doesn't matter
SA = surface area of rectangular prism
SA = 2*(LW + LH + WH)
SA = 2*(2*6 + 2*9 + 6*9)
SA = 2*(12 + 18 + 54)
SA = 2*(30+54)
SA = 2*(84)
SA = 168 square cm
