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

dont know why u stopped there what is 21609*90? 1944810
then what is %281%2F3%291944810? highlight%28648270%29
the full equation looks like this
V=%281%2F3%29%28B%29%28H%29%29
V=%281%2F3%29%28147%5E2%29%2890%29%29
V=%281%2F3%29%2821609%29%2890%29%29
V=%281%2F3%291944810
V=highlight%28648270%29
