Area of one triange x itself x itself ?
.
.(1/3)b²h
That is off the top of my head from my geometry class that I had over 4 years ago. That I literally slept through. cbf to actually do the math though.

@Alen Heartview said that. I just liked your thread and it just fell on my mind why wouldn't I make a similar thread, but about geometry since I love math. Thats all.

So the answer is 225.7707785, so lets say 225.77..
Am i right?
Am i right?
YES! THE ANSWER IS CORRECT!!!! HERE IS THE EXPLANATION:
Base of a regular four-sided pyramid is a square with sides of length a=8m with a diagonal long 8√2m. (diagonal is the length of the side * √2)
Consider the triangle that makes up half the diagonal length: d/2 = 8√2 = 4√2m, the lateral edge of the length b=12m and the height "h".
The Pythagorean theorem states:
b^2 = h^2 + (d/2)^2
We get that:
12^2 = h^2 + (4√2)^2, it follows that h =√112 = 4√7m
Now we can calculate the volume:
V = 1/3 * B * h = 1/3 * a * h^2 = 1/3 * 8^2 * 4√7m^3 = 256/3√7m^3 = 225.77m^3

at first i did 0.33 * 8 * 8 * 10.58, which sounded to be the same as 1/3..
When i did 8 * 8 * 10.58 / 3.. the correct answer showed up..
Weird..
