Answer:
872 square in.
Step-by-step explanation:
The formula for the surface area of a rectangular prism is:
![A=2(wl*wh*lh)](https://tex.z-dn.net/?f=A%3D2%28wl%2Awh%2Alh%29)
Where w is the width of the prism, l s the length of the prism, h is the height of the prism, and A is the surface area.
Plugging in the numbers given, you get the following equation:
![A=2((20*18)*(20*2)*(18*2))](https://tex.z-dn.net/?f=A%3D2%28%2820%2A18%29%2A%2820%2A2%29%2A%2818%2A2%29%29)
Which when calculated out, is 872 square in.
