Answer and Step-by-step explanation:
To find the surface area, all you have to do is find the area of each face of the prism, and then add them all together.
15 x 20 = 300
(15 x 8)/2 = 60
(15 x 8)/2 = 60
(There are two triangles)
8 x 20 = 160
20 x 17 = 340
Now, add them all together.
300 + 60 + 60 + 160 + 340 = 920
The surface area of the prism is 920 [tex]units^{2}[/tex]
