GEOMETRY The volume of a pyramid can be found by multiplying the area of its base B by one-third of
its height. The area of the rectangular base of a
pyramid is given by the polynomial equation
B = x2 - 4x - 12.
a. Write a polynomial equation to represent the volume of the pyramid V if its height is 10 meters. Write your answer in standard form.
V=_

Part B:
b. Find the volume of the pyramid if x=12 m.
