![\boxed{=2x(x^2+6y^2)}](https://tex.z-dn.net/?f=%5Cboxed%7B%3D2x%28x%5E2%2B6y%5E2%29%7D)
Step-by-step explanation:
Remember:
![(a+b)(a-b)=a^2-b^2\\\\a^3+b^3=(a+b)(a^2-ab+b^2)\\\\\\(x+2y)^3+(x-2y)^3\\\\=(x+2y+x-2y)((x+2y)^2-(x+2y)(x-2y)+(x-2y)^2)\\\\=2x(x^2+4xy+4y^2-(x^2-4y^2)+x^2-4xy+4y^2)\\\\=2x(x^2+6y^2)\\](https://tex.z-dn.net/?f=%28a%2Bb%29%28a-b%29%3Da%5E2-b%5E2%5C%5C%5C%5Ca%5E3%2Bb%5E3%3D%28a%2Bb%29%28a%5E2-ab%2Bb%5E2%29%5C%5C%5C%5C%5C%5C%28x%2B2y%29%5E3%2B%28x-2y%29%5E3%5C%5C%5C%5C%3D%28x%2B2y%2Bx-2y%29%28%28x%2B2y%29%5E2-%28x%2B2y%29%28x-2y%29%2B%28x-2y%29%5E2%29%5C%5C%5C%5C%3D2x%28x%5E2%2B4xy%2B4y%5E2-%28x%5E2-4y%5E2%29%2Bx%5E2-4xy%2B4y%5E2%29%5C%5C%5C%5C%3D2x%28x%5E2%2B6y%5E2%29%5C%5C)

Answer:
367.2 cm²
Step-by-step explanation:
First, you need to find the area of the lateral surfaces, since each one is a 5cm by 6cm rectangle, all you need to do is multiply to find the area of one of them, and then multiply by 6 to find the area of all 6 sides.
lateral area = 5cm * 6cm * 6
lateral area = 30cm² * 6
lateral area = 180 cm²
Next, you need to find the total surface area by multiplying the area of the base by two and adding that to the lateral surface area.
SA = 180cm² + 2(93.6cm²)
SA = 180cm² + 187.2cm²
SA = 367.2cm²
The total surface area is 367.2 cm².
It’s the first one if it’s not then my bad g
