Can you figure it out how the Egyptians build a piramid in only 20 years without these trucks to haul these big rocks they used?... 

The bed size on that truck is about H 10', W 20', L 30'. Giving that rock a size of about 20'x20'x10'.
The average size of the largest stones in the pyramids were 5'x8'x12'. Most stones were about 5'x5'x8'. There is just a slight difference in the size. HTH.
