Hi,

I'm new here and am looking for some help.

I'm trying to find the volume and surface area of a triangular prism.

The triangle is 1.25m wide and 1.7m high

The rectangle is 2m wide and 1.81 m high.

Does anyone know the formulas I have to use?

I have the answer here, I'm just not sure how to do the working.

Thanks.
