The surface area<span> of any </span>prism<span> is the total </span>area<span> of all its sides and faces. A </span>triangular prism<span> has three rectangular sides and two </span>triangular<span> faces. </span>To find<span> the </span>area<span> of the rectangular sides, use the </span>formula A = lw, where A = area, l = length, and h = height.
The formula  <span>A=<span>1/2 </span>bh</span><span> </span>
        
                    
             
        
        
        
7B+5Y=487B+1Y=40Subtracting Eqn 2 from 1 we get 4Y=8so Y = $2 and X=$38/7
