I am so confused about this I keep-getting this kind of question wrong plz help

D. 100 + 40 + 40 + 40 + 40

Step-by-step explanation:

Ok, so lets start with surface area. It's a simple term really. Just the area of each shape on the "face" of the 3d object.

It's easy to tell what the shape on the bottom of the pyramid is because well, it's a square pyramid.

10 x 10 = 100

Since it's a square pyramid, the 4 sides all have to come up at some point, meaning that you'll want to multiply the answer to one of the triangles by 4.

So, what is the area of one of the triangles?

All you have to do multiply bh, and divide by 2. The formula looks like this:

bh1/2

So, 8 x 10 = 80/2 = 40. The area of one triangle is 40. Multiply that by 4 and you get 160, for the total surface area being 260.

But it's not looking for that, it's looking for the areas of all the shapes added together, but not solved. so it's just:

hope this helps, brainliest is appreciated.
