If each edge of a cube is doubled, then its volume :	Choose the correct answer:
A) Becomes 8 times  B) Becomes 9 times  C) is double  D) Becomes 6 times  E) None
Sol.   Let original edge = a. Then, volume = a³   New edge = 2a. So, new volume = (2a)³ = 8a³   ∴ Volume becomes 8 times   Becomes 8 timesnswer Becomes 8 times
