    Answer:

    236 in squared

    Step-by-step explanation:

    You can separate the shape into two rectangular prisms.

    prism 1 – 9, 2 ,4

    prism 2 – 4, 2, 8

    Since the frosting is on the outside of the cake you have to find the surface area.

    To find the surface area you use the equation:

    2(wl + hl + hw)

    Put in the values you know:

    2(9 * 2 + 4 * 2 + 9 * 4)

    multiply:

    2(18 + 8 + 36)

    Add:

    2(62) = 124

    Now you find the surface area of the second prism.

    2(4 * 2 + 2 * 8 + 4 * 8)

    Multiply:

    2( 8 + 16 + 32)

    Add:

    2(56) = 112

    Now add the two surface areas to get the surface area of the whole shape.

    112 + 124 = 236

    The answer is 236 in squared
