which one do you want to do?

We can start on the first one if you don't mind:) I just don't understand them.

Use formulas to find the lateral area and surface area of the given prism. Round your answer to the nearest whole number.
lateral area is the "side area" , which is the area not including the "top or bottom"
That is not very clear, but we we assume the top and bottom are the triangles
and that means the "sides" are the 3 rectangles.

23 and 9

and the area of a rectangle is length * width
so the area of the bottom side is 23*9

Which sides do you do this to?

And the top would be 23*12.04?

yes

Do we need to do the back too? If we did then I think it would be 8*23

Ok. Is there a reason why the rectangles couldn't be the top and bottom?

Ok that makes sense

so the lateral area will be 207+276.92 + 184= 667.92
rounded to the nearest whole number: 668

the surface area is the total area. so add 72 to the lateral area to get the surface area

Would I need to add 72 or 144?

the area of a triangle is 1/2 base * height

Oh I left out the 1/2. I get it now

Would you like me to make a new question for the next one or do you want to just stay here?

please make a new post. they get too long otherwise.

Ok I'll tag you in it. Thank you so much!
