I'd like to know how long, how many hours total, it took for this nose, because that might give us an idea of how long it took to carve the Great Sphinx.

NARRATOR: Although Brown had resorted, at times, to using modern machinery to speed up the carving, he's gone to great lengths to work out how long it would have taken using just ancient tools.

RICK BROWN: We calculated that we could do 200 hits in five minutes, over and over again, and sustain that for an eight-hour day.

NARRATOR: By measuring the amount of stone chipped away, he can calculate how much stone one worker could remove.

RICK BROWN: It would take 40 hours for one person to remove one cubic foot of stone.

NARRATOR: Based on Lehner's scale drawing, they calculate how much stone was removed from around the Sphinx.

MARK LEHNER: So that big block and that big block, you got those out of there.

NARRATOR: From there, it's a lot of math to get to the final figure for how long it would have taken to carve the whole Sphinx.

MARK LEHNER: A hundred carvers, three years.

NARRATOR: But by carving the scaled-down nose, Brown and Lehner have discovered that those 100 people for three years is just one part of a greater enterprise.

To build the great Sphinx there must have been an army of people cutting wood to stoke fires and forges, making tools, sharpening tools, running them back and forth, and pounding away at the giant rock that would become the Sphinx.
