Question

The great pyramid height 500' has a square base 800 by 800. Find the area A at height h (500').

Answer 1

So.. Find A at 500 (feet?)
well, if it were a perfect pyramid, the area at the very top would be so small as to be 0 - it would be practically 0*0 If you want to know how to find the area at any given height...
The area of a infinitely thin slice of it would steadily decrease as you go up, at a rate of
1.6 (the length of each side decreases by 1.6 feet for each foot travelled upwards)
therefore, you get:
A = (800-1.6h)^2.
(I think)

Answer 2

Yeah, that makes sense to me I had something similar to this so I just needed clarification in a sense
