WHAT IS THE SURFACE AREA OF THE PRISM?

Answer 1

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.
