soln,
here area of base = 25/4 unit ^ 2
height of the prism = 8/5 unit
so, 
volume of prism = area of base x height of the prism
 


so the volume of the prism is 10 unit^2
 
        
             
        
        
        
4a - 3b
4(5) - 3(- 2)
20 + 6

25 * 5 + 15 * 3 - 40 * 2 =
125 + 45 - 80 = 
170 - 80 =
90
