Question 300589
One of the stone pyramids in Eygpt has a square base that measure 147 meters on each side. The height is 90 m. What is the volume of the pyramid. 
Now I know that V=1/3B. 
I have gotten V=one third 21609*90. What is confuseing me, is how to work the problem from there. 


The formula for the volume of a pyramid is (1/3)*height*base area

The base has area of 147*147 = 21,609 so the volume is:

(1/3)*90*21609 = 30*21690 = 650,700
