Step-by-step explanation:
Surface area of rectangular prism:
length = l = 20 in
width = w = 12 in
height = h = 5 in
![\boxed{\text{surface area of rectangular prism = 2*[lw + wh + hl]}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Ctext%7Bsurface%20area%20of%20rectangular%20prism%20%3D%202%2A%5Blw%20%2B%20wh%20%2B%20hl%5D%7D%7D)
= 2* [ 20*12 + 12*5 + 5*20]
= 2* [240 + 60 + 100]
= 2 * 400
= 800 in²
