If a half-full 4-inch by 2-inch by 8-inch box of soymilk is poured into a right circular cylindrical glass with radius 2 inches, how many inches high will the soymilk reach? (Assume that the capacity of the glass is greater than the volume of the soymilk.)
Equate half-the-volume of the rectangular box to the Volume of the cylinder
(l.b.h)/2 = Pi.r.r.h
(4 X 2 X 8)/2 = Pi.2.2.h
(2 X 8)/2 = Pi.h
8 = Pi.h
h = 8/Pi
Answer is Choice D.
