Question

Find the surface area of the composite figure

Answer 1

Answer: I believe it is 508 cm²

Step-by-step explanation:

Start out by finding the surface area (SA) of the 2 shapes. The formula for SA is 2(wl + wh + wh).

Blue shape: 2(12x2 + 12x10 + 2x10) = 328 cm²

Red shape: 2(8x3 + 8x6 + 3x6) = 180 cm²

Now that the surface area of both shapes are solved, just add them together and you will get the answer of 508 cm²

I don't know if this is the right answer

Answer 2

412

Explanation:

`2(12 * 2 + 10 * 2 + 12 * 10) + 6 * 3 * 2 + 8 * 3 * 2`

`= 2(164) + 36 + 48`

`= 328 + 84`

`= 412`
