pyramid

Rectangle ABCD is the base of pyramid PABCD. If AB=8, BC=4, PA perpendicular to AD, PA perpendicular to AB, and PB=15. Then what is the volume of PABCD?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

AB = 8       BC = 4        PB = 15

 

Height      PA = sqrt(PB² - AB²)

 

Volume      V = 1/3(AB * BC * PA)
