To find the surface area of the prism, we need to find the area of each face and then add them together.
There are two faces with dimensions 15mm x 4mm, which gives us:
2(15mm x 4mm) = 120mm²
There are also two faces with dimensions 15mm x 3mm, which gives us:
2(15mm x 3mm) = 90mm²
Finally, there are two faces with dimensions 4mm x 3mm, which gives us:
2(4mm x 3mm) = 24mm²
We add all these areas together to get the total surface area of the prism:
120mm² + 90mm² + 24mm² = 234mm²
Therefore, the surface area of the prism is 234mm².
