Answer:
1428[tex]cm{2}[/tex]
Step-by-step explanation:
We first find the surface area of the triangle=base times height/2
height=8
We add 15+6=21, 21 times 8=168/2=84
We have 84 for this triangle, so the other triangle's area would also be 84
Now we find the area of the rectangle on the bottom-30 times 15=450
We then find the area of the other rectangle on the right side of the prism=30 times 17=510
Finally the area of the left-side of the prism=30 times 10=300
For the surface area, we add these all up=84+84+450+510+300=1428
