First, let's calculate the triangles of the prism.
The area of a triangle is base times height, then divide by 2.
So:
(7*8)/2.
This would give us 28.
Also knowing that there are two triangles on the prism, we have to multiply 28 by 2. This would give us 56.
Now, for the rectangles, we have to find their areas.
The area of a rectangle is length times width. So this would give us:
8*16.
This equals 128.
Next, knowing that there are three rectangles, multiply 128 by three. This gives us 384.
Now, we jus have to add all the areas together:
384+56 = 440
So the prism's surface area is 440cm^2
Hope this helps. If you have any questions, please put them in the comments below.

C is the only correct answer
Answer:
From narrowest to widest graph, the order is f(x) = –10x², f(x) = 2x², f(x) = 0.5x²
Step-by-step explanation:
I graphed the functions below
f(x) = –10x² is the black line, f(x) = 2x² is the red line, and f(x) = 0.5x² is the blue line.

Answer:
90° is correct answer. :)
A bi-millennium means two (bi) times thousand of years (millenium), this means that a bi millennium has 2000 years in it: two thousand years.
The origin of this word is latin: because of this it also has the plural of "bimillennia" <span />
