Answer:
Prism A:

Prism B:

Step-by-step explanation:
Given
See attachment for prisms

Required
Determine the surface area of both prisms
Prism A is triangular and as such, the surface area is:

Where

and

Such that a, b and c are the lengths of the triangular sides of the prism.
From the attachment;

So, we have:




Also:




So:



Prism B is a rectangular prism. So, the area is calculated as:

From the attachment


So:
