Its not specific to pyramids - its true for stretching any shape in 2D and 3D or lines 1D. Stretch it to twice its former size across a single axis and you get double the length/area/volume.
It becomes obvious in 2D if you look at how the area of a rectangle is calculated (x*y) and imagine your shape is just projected/drawn on that rectangle and stretches with it.
- ilovepyramids 7y agoI did consider this, and it seemed to make it feel a little clearer—but when I first posted, I didn't feel it was obvious that the fraction of the rectangle occupied by the triangle would remain constant if you stretched it. But I think the other replies prove that that is true. Thank you.
