Atypical stone on the lowest level of the great pyramid in egypt was a rectangular prism 5 feet long by 5 feet high by 6 feet deep and weighed 15 tons what was the volume of the average stone how much did one cubic foot of this stone weigh

To find the volume, you need to do length times width times height
SO you have to do 5 times 5 times 6
The volume is 150 cubic feet
Since 150 cubic feet of this rectangular prism is 15 tons
you can do 15 divided by 150
so one cubic feet of this stone sculpture weight 0.1 tons
Btw, a pyramid is  a triangular structure, not rectangular

The mode of the numbers is 29.
