volumeBox w h d = w * h * d
One approach for the Giza problem is starting from the pyramid volume and the estimated stone volume. Using general functions for the task, that might look like this in GHCi:
Prelude> let volumeBox w h d = w * h * d -- Just as above. Prelude> let volumeSquarePyramid b h = b * b * h / 3 Prelude> volumeSquarePyramid 230.4 146.5 / volumeBox 1 1 1 2592276.48
