**Reiny**, Monday, March 10, 2008 at 11:17pmlet the height be x feet

then the length of building is x+148 feet

vol of pyramid = (1/3)base*height

= (1/3)x(x+148^2 = 28933800

You will get

x(x+148)^2 = 89,801,400

expand this and you will have one nasty equation.

It is highly unlikely that it will factor, so you are stuck with using one of the methods of solving a cubic.

If you are familiar with it, Newton's Method is very good
