7000 of which one? They are different sizes.
cant decide which is a worse measurement, pyramids of giza or the acre-foot.
one of them is a fractal volume in the general shape of a pyramid, but most people have no scale of size for it. also, it seems to be plural, which just makes it more confusing.
the other one is defined as a one foot by one acre volume, with an acre being one furlong by one chain, with those being 660 and 66 feet respectively.
Who measures water in “great pyramids”?
You could have as well used melons as a measure of volume.
