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
