A cube has a volume of 216 cubic feet. If a similar cube is twice as long, twice as wide, and twice as high, then the volume, in cubic feet of such cube is? Pick:
A) 24  B) 1728  C) 64  D) 80  E) 100

Rationale: "volume = 216 = side ^ 3 i . e . side of cube = 6 new cube has dimensions 12 , 12 , and 12 as all sides are twice of teh side of first cube volume = 12 * 12 * 12 = 1728 square feet answer : option b"
Answer: B
