Question

Someone help pleaseeee

Answer 1

1428
`cm{2}`

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
