    The bottom rectangle does not have dimensions but I am going to it is 15 x 9

    Since this is a 2D image, Surface Area is just Area

    Total Area = Area of 2 triangles + Area of 3 rectangles

    TA = 2( ½bh) + 3(LW)

    TA = 2( ½*9*8) + 3(15*9)

    TA = 72 + 405

    TA = 477 sq. units

    The total surface area:

    3*135 + 2*36 = 477
