We're asked for the ratio of the volume of the cube to the volume of the cylinder. This question requires a couple of formulas and can be solved by TESTing VALUES. IF.... Side of the cube = 2 Radius of the cylinder = 1 Height of the cylinder = 2 Volume of the cube = (side)^3 = (2)^3 = 8 Volume of the cylinder = (pi)(R^2)(H) = (pi)(1^2)(2) = 2pi Ratio of cube volume to cylinder volume = 8:2pi = 4:pi Final Answer: C GMAT assassins aren't born, they're made, Rich _________________ Contact Rich at Rich.C@empowergmat.com • Free Veritas GMAT Class Experience Lesson 1 Live Free Available with Beat the GMAT members only code • Free Practice Test & Review How would you score if you took the GMAT Available with Beat the GMAT members only code • Free Trial & Practice Exam BEAT THE GMAT EXCLUSIVE Available with Beat the GMAT members only code • Magoosh Study with Magoosh GMAT prep Available with Beat the GMAT members only code • 1 Hour Free BEAT THE GMAT EXCLUSIVE Available with Beat the GMAT members only code • Award-winning private GMAT tutoring Register now and save up to$200
