24(height) cm 3.5(length) cm 13(width) cm find the surface area of the prism

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. :)
