Answer:
![\huge\boxed{SA=2466\ (mm^2)}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7BSA%3D2466%5C%20%28mm%5E2%29%7D)
Step-by-step explanation:
The formula of a Surface Area of a rectangular prisms:
![SA=2(lw+lh+wh)](https://tex.z-dn.net/?f=SA%3D2%28lw%2Blh%2Bwh%29)
<em>l</em><em> - length</em>
<em>w</em><em> - width</em>
<em>h</em><em> - height</em>
<em />
We have:
![l=39mm;\ w=12mm;\ h=15mm](https://tex.z-dn.net/?f=l%3D39mm%3B%5C%20w%3D12mm%3B%5C%20h%3D15mm)
Substitute:
![SA=2\bigg((39)(12)+(39)(15)+(12)(15)\bigg)\\\\SA=2(468+585+180)\\\\SA=2(1233)\\\\SA=2466\ (mm^2)](https://tex.z-dn.net/?f=SA%3D2%5Cbigg%28%2839%29%2812%29%2B%2839%29%2815%29%2B%2812%29%2815%29%5Cbigg%29%5C%5C%5C%5CSA%3D2%28468%2B585%2B180%29%5C%5C%5C%5CSA%3D2%281233%29%5C%5C%5C%5CSA%3D2466%5C%20%28mm%5E2%29)
