To find the surface area you will need to find the area of all 5 surfaces (faces) on the prism.  On a triangular prism there are 2 triangular faces and 3 rectangular faces.  All 3 rectangular faces are the same and the 2 triangular faces are also the same.
To find the area of the triangular faces, you will use the formula for finding the area of a triangle:
A = 1/2bh
     1/2 x 10 x 8.7
A = 43.5 in^2 
To find the area of the rectangular faces, you will use the formula for finding the area of a rectangle:
A = bh
    10 x 3
A = 30 in ^2
30 + 30 + 30 + 43.5 + 43.5 = 177

Some symbols are missing. I'm assuming you meant to put in a horseshoe symbol like so 

If so, then the contrapositive of that would be 

 which is the final answer. 
The tilde sign 

 means "not" so writing 

 means "not q" which is the complete opposite of q.
