Answer:
2395 cm²
Step-by-step explanation:
You need to find the area of each side of the prism.
the first side is 3.5x24 which equals 840. there are two of those sides since it's a prism, so multiply by 2. 840x2=1680.
the second side is 13x3.5 which is 45.5. multiply that by 2 for the other side, 45.5x2=91.
repeat for the third side: 24x13=312. 312x2=624.
add all of the sides up to get total surface area. 624+91+1680=2395. :)
