Question

3-d coordinate graph pyramid volume?

Answer 1

I'm not sure how to go about solving it; I'm sure I could find the answer if I knew how to; I'm studying for finals and I don't even remember covering this in class. :(

Answer 2

if you see the coordinates for the bottom square. The side of the square extends from
- 50 in x to + 50 in x = so the side length is 100

similarly the width of the square -50 in Z to + 50 in Z so side length is 100. So the base is a square of 100 x 100

Now to find the height of the pyramid. so the height is 80

Answer 3

So now it is easy to find the volume using the formula

V = (1/3) B.H ; B = Area of Base, H = Height of the Pyramid

Oh thank you, I have loads of these in my problem textbook but I never learned how to do them.
