god that girl in mid right ruins this whole gif. she exaggerates way too much and stands out compared to the others. if she really toned it down it would be perfect

Try drawing it. The geometric figure has a lot of symmetry, so what you can do is figure out the area of part of it and multiply by a factor (to be figured out by you) to get the total volume.

>figure out the area of part of it
I meant volume, not area. Sorry about that.

Also, if you google octahedron it will give you an idea of what your picture should look like.

I would just integrate x^2 / 2 from 0 to 1, and then multiply by 8 , to get 4/3.

it's 2/3 dumbass. whatever units.

do you have to use a double integral for this? because it's actually just a 6th grade math problem.

the vertices form an eq.triangle. So calculate the volume of that pyramid. then double it.

square in the xy plane has side sqrt(2), so area 2. The pyramid above the xy plane has volume 1/3*base*height=1/3*2*1 = 2/3. Double that... 4/3?

You can think of it as 2 pyramids.
The total volume is then $V= \frac{2}{3} A_{b} h$ . Well from the vertices, the sides of the square base are all ?2 so $A_{b} = 2$ and the height h is 1. So the volume is 4/3, no integration needed.
