Rather, the appropriate parameter islifting work measured in Joules – in brief, the product of mass multiplied by lifting height. Provided lifting of a block tookon average the same time at the 4th dynasty pyramid construction sites, then there was a proportion between lifting workand building time. The upper limits of the resulting building times depend on the length of Kheops’s reign.
