Answer:

408in²

Step-by-step explanation:

Hello!

We can see that there are two sides with the side lengths 4in and 0.5ft(6 in), two sides with side lengths 4in and 1.5ft(18in), and two sides with side lengths 0.5ft(6in) and 1.5ft(18in). Multiply and add to find the Surface area (Area of all six faces)

Find the Surface Area:

  • SA = 2(l * w) + 2(l * h) + 2(w * h)
  • SA = 2(6in * 18n) + 2(6in * 4in) + 2(18in * 4in)
  • SA = 216in² + 48in² + 144in²
  • SA = 408in²

The surface area is 408in²
