WebHere are a few answers. 1. If you cut vertically down from the vertex of a pyramid, you get a triangle. You don't always have to cut a pyramid at the same angle either, straight up and down. If you cut horizontally, you would get a rectangle. If you instead cut the rectangular pyramid at an angle, you could get anywhere from a kite to a pentagon. WebSo it'll be 3.92. I'll just use this expression for the volume as a function of x. 3.92 times 20 minus 2 times 3.92 times 30 minus 2 times 3.92 gives us-- and we deserve a drum roll now-- gives us 1,056.3. So 1,056.3, which is a higher volume then we got when we just inspected it … WebA plane is a flat surface that extends forever in all directions. A cross section is the intersection of a three-dimensional figure and a plane. Imagine a plane slicing through the pyramid shown, or through a cone or a prism. The figure given below shows the intersection of a cone and a plane. The cross section is a circle. ims pegs warrior
